How to connect speakers to a car radio

Every car enthusiast who values high-quality sound should know the basics of installing an audio system. Today, not all cars are equipped with radios, so drivers have to install the speakers themselves. How to connect speakers to a car radio, how to position the speakers correctly and what you need to know about wire insulation - read below.

Learning to distinguish between plugs

How to install an audio system in a car, how are the wires connected and is an amplifier needed? Let's figure out which plugs can be used for installation. Plugs may have different markings depending on the standard. ISO marking is typical for multimedia systems and wiring in cars; if such a device is used for other purposes, it may break. Most manufacturers make their own adapters for the ISO standard, so there are many different plugs available commercially.

Before you install speakers in your car, you need to understand which plugs to use. Each individual car is characterized by original adapters with which the speakers must be connected to the radio in the car. If standard wiring is installed, it is possible that the audio system can be connected to it. To connect the speakers in the car to the new radio yourself, use a Euro standard adapter.

Installation of 2 din radio

The situation is somewhat different in the case when a 2 din standard radio tape recorder claims to replace the old radio. The installation procedure for such a radio will be painless if the old analogue meets the same standard. Otherwise, a number of problems may arise.

Firstly, if you replace the standard 1 din standard configuration with 2 din, you will have to replace a number of elements: the center console, frame, etc.

In addition, during these events you will definitely encounter various undesirable phenomena that will not have the best effect on the aesthetic component of the interior of your car.

Based on all of the above, it is quite reasonable to draw one single conclusion: select an audio system that meets the standards provided by the manufacturer of your car.

Car radio installation steps

It is no secret that the battery is the main source of power for the on-board grid of a car, but a battery malfunction can lead to damage to the car radio. To prevent equipment failure, you need to know how to properly connect the device yourself. During installation of the system, do not allow the positive contact of the battery to touch the negative or the speaker terminal. Experts do not recommend powering the device with plus or minus from the cigarette lighter or ignition switch.

Before connecting the speakers, it is necessary to take into account that the system connection will be optimal only to the battery. Thanks to this, you will be able to rid your speakers of various interferences and speakers, and it will be possible to operate them at full power. To make the connection, it is better to use a short copper stranded cable; its cross-section should be at least four mm2. On this wire, if it goes to the speakers or amplifier (not important), you need to install a fuse, which should preferably be located 50 cm from the battery. The wiring should be installed away from energy consumers; the wires should not be twisted - first of all, they are connected to the speakers, and then to the radio.

Sound settings

The sound setup process includes the use of 2 work scenarios:

Speaker systems are different. Some play directly from the radio, using all available software functions, but there are also those that connect to an external amplifier and have their own sound card.

Setting up speakers without an amplifier is a labor-intensive, but doable process. You need to put on your favorite music, the sound of which the tuner knows well. It needs to be made quieter or louder until the speaker system begins to make foreign noises, such as wheezing or clicking. Depending on the interference, measures will need to be taken. Some solve them programmatically, while others struggle with electricity and all sorts of machine shortcomings. Most of these problems can be solved by installing grounding.

If you set up acoustics using an amplifier, then you need to gradually change ready-made presets. All this is reminiscent of setting up recently purchased headphones with a sound card. By changing the voltage, you can achieve clear, high-quality sound in a short period of time. The amplifier in this case plays a supporting role.

The most important thing: if you are not sure that you can handle it on your own, then it is better to seek help from a specialist.

Connecting the speakers

Installing speakers to the radio is an important point. To prevent mistakes, during the repair process there should be a speaker connection diagram nearby, which marks all the points of correct installation. When connecting the front or rear speakers, pay attention to the markings on them, thanks to which you can find the positive and negative terminals. Manufacturers usually make the positive output wide and the negative output narrow.

Wiring selection

The wires for the speakers or loudspeaker are marked - there can be 2 or 4 pairs. If the wire is a single color, it is positive; if it has a black stripe, it is negative. A single color must be connected to the wide terminal of the speaker, and with a strip - to a narrow one. The negative wire can be common to the side or front speakers (up to 20 W). If the speaker system is more powerful, each channel should have its own negative and positive wires. These cables cannot be swapped or connected to the car body, that is, grounded, as this will lead to a deterioration in sound quality.

Low-power devices may be equipped with four colored cables, but may not have a striped wire. If this is the case, then the negative terminal of the speakers is connected to the negative terminal of the car radio. If you make a mistake, it can not only lead to poor sound quality, but also short circuits in the wiring, which can lead to a fire. Most radio tape recorders are supplied with connecting cables, but experts recommend using them only for testing, since their cross-section is small. The operation of such wires is relevant if the power of the audio speaker is no more than 20 W; usually the diameter of such speakers is 13 cm.

Insulation Features

If you use high-quality wiring, it will be equipped with good insulation. The insulating background should be silicone; this will prevent the wiring from cracking at sub-zero temperatures. The cable cross-section must correspond to the power of the car radio. Wiring should be installed away from other energy users. Fractures and twisting of cables are not allowed. The wiring should not fray; it should be laid closed - in the door pillars, under the thresholds.

Stories from our readers

The advantages of the speakers include ease of installation - every car owner can connect the tweeters correctly. Holes are made in the door and body for rubber corrugation, which will prevent chafing and breaking of wires. Pull the acoustic wire into the corrugation using steel wire.

The location of the amplifier and equalizer on an additional shelf under the glove box allows you to minimize the length of the power cable.

Tools To connect the tweeters to the radio or crossover you will need: cable;. Subwoofers of the closed type, having a sealed housing closed Subwoofers of the bass reflex type vented, are characterized by the presence of a bass reflex - a slot or pipe that serves to adjust the frequency response in the low frequency region Subwoofers of the bandpass type - differ from the above in that the speaker itself is retracted inside the subwoofer housing, and the sound radiated through a bass reflex subwoofer with a passive radiator have an additional diffuser or speaker without a magnetic system, which serves to lower the overall resonant frequency of the loudspeaker.

Choosing a location Initially, you will need to decide on a location for the future speaker system. Another option is to route the wires using a crossover frequency filter. We strongly advise you to do this so that your passengers are not irritated by rattling plastic, which will react this way to loud music coming from the speakers.

To help car enthusiasts

It is enough to use the correct connecting cables and not make the wrong polarity when connecting. In order for the sound from both sides to be perceived at the same volume, you can use balancing to increase the sound volume of the right speakers. The driver of the car sits on the left, and is closer to the left speakers.

Bridged connection of amplifier channels is a connection in which 2 amplifier channels operate on 1 speaker. Compared to the previous class, the efficiency of this is almost 2 times higher, but high distortion in the output signal makes it rarely used. The photo shows a cross-section of a classic low-frequency electromagnetic loudspeaker.

There is one more problem. A subwoofer is a large-sized element, very labor-intensive to manufacture and install. First, let's look at the characteristics that are indicated in the passport.

These can be the following components: Amplifier Speaker systems Subwoofer This set of technical means allows you not only to increase the sound volume, but to significantly improve the quality of music playback. Rated electrical power is the power that the speaker can reproduce for a long time without distortion. How to connect an odd number of speakers

Speaker placement

When installing high power rear channels, they must be installed correctly. Oval speakers are mounted on the rear parcel shelf so that the speaker axis is directed diagonally across the vehicle. The rear right column should be aimed at the driver, and the left column at the front passenger. Only after proper installation has been carried out can the speakers be connected to the audio system.

To ensure high-quality sound, the speakers cannot be covered - they need more space for normal operation. As for tweeters, they need to be installed on the windshield pillars. If you mount them away from low-frequency speakers, you can achieve a bright quad effect. The direction of the tweeters is done in the same way - the front left one is directed towards the passenger, and the right one - towards the driver. The wiring must be secured securely.

How to connect speakers to a car radio

Car owners often ask how to connect speakers to a car radio. It turns out that there is nothing complicated in this procedure. It is enough to know the basic rules and follow the instructions below. Having learned how to connect speakers to a car radio, you no longer need to contact specialists because of this. Why do you think it is necessary to connect new speakers to a standard car radio? The answer suggests itself: for many drivers, music becomes an integral part of life. But a meager speaker system, consisting only of inexpensive standard speakers and the same car radio, will not be able to provide the required sound level. Then you have to change everything: buy new speakers, more powerful ones, and a modern car radio with various bells and whistles. There is another reason: some motorists want to connect more speakers. For example, they want to know how to connect 6 speakers to a car radio or all 8.

Note. Connecting speakers to a car radio is a responsible process, but not complicated. Even a beginner who has never done this before can handle this task quite well.

Theory. Connection types

In electrical engineering there are two types of connections - series and parallel. With a series connection, the resistance is summed up; with a parallel connection, it becomes lower than the smallest of the connected ones. This is something worth remembering and will come in handy in order to connect your speakers correctly.

Basic formulas for parallel and serial connections

There is also a mixed connection. This is when serial chains and parallel connections are “mixed”. In this case, calculation formulas are used, gradually arriving at one of the “pure” circuits - parallel or sequential.

The figure shows the sequential transformation of a complex mixed connection into a simple one.

Connection

How to connect speakers to a car radio

So, in order to connect these two components of the acoustic system with each other, you will first need to arm yourself with the required tools. Below is the list:

A good speaker cable (you should never skimp on it and the more expensive it is, the better the sound will be);
Corrugation;
Some kind of insulating material;
Drill and drill bits;
Special tester.

How to connect speakers to a car radio

Start

Let's start the operation:

The first step is to decide on the location of the purchased speakers. If the car already has seats provided by the manufacturer, this is considered a big advantage.

Note. As a rule, the front speakers should be located on the edges of the dashboard or in the car doors. Both options are good, but the second is much more popular and involves firmly fixing the speakers. For this purpose, an additional acoustic podium is built into the door.

As for the second pair of speakers, they, as you might guess, are installed at the rear, mainly on the trunk shelf. Just like with doors, this involves modification. The standard decorative shelf is dismantled, and in its place a real acoustic shelf is installed with podiums (see DIY acoustic podiums) for the speakers.

Wiring

The next stage of the operation is electrical wiring. So, if the manufacturer did not provide holes for the electrical cable in the doors, you will have to drill them yourself.

Connecting speakers to a car radio

Note. It is very important to remember that the cable must not be pulled through metal or even plastic without protection. This leads to a short circuit. Therefore, special gasket rings are installed, which must be fixed very firmly on the inside.

To make it easier to route the cable to the rear speakers, we use the edges of the car. Under no circumstances should cables be laid under rugs. It is best to tape it with electrical tape to the general wiring, having first dismantled the car trim and dashboard;
The speaker cable itself must be carefully insulated. After tensioning the corrugation, the wire is immediately marked: which speaker it should go to - front or rear. This approach to the matter will greatly facilitate connecting the speakers at the final stage of work;
After the car trim is disassembled, take the wire and tighten the cable inside. If the cables are intended for rear speakers, then we run them along one side and secure them with plastic clips for reliability.

How to properly connect speakers to a car radio

Note. Like it or not, some pieces of wire will go along the floor. In these places, it is best to wrap them with durable corrugation, for example, the one used to protect electrical cables.

It is important to label the wires, especially if you use cables of the same color. In this case, we also do not forget about the negative wire, which can be marked red or some other color.

The final stage of work

After the wires are marked, we take a tester and check them for absence of short circuit;
If everything is in order, then we connect the wires to the connectors, and mount the head unit in its place.

Note. It is strictly forbidden to carry out all the connection manipulations described above while the battery is on!

It's time to check the speakers themselves for resistance. As a rule, it should not exceed 4 ohms. If everything is fine, then we put the speakers in the places intended for them, and then connect the wiring.

Note. At this stage of work you need to be extremely careful. The fact is that the speaker terminals should under no circumstances touch the metal elements of the machine.

Now we check the operation of the entire speaker system.

When carrying out connection work with your own hands, it is important to use visual aids. Video reviews and photos - materials, step-by-step instructions and drawings will be very helpful. The price of the issue in this case is practically zero, because you don’t have to pay for services, but you just need to buy some materials for the work.

Many car owners are not satisfied with the quality of the standard audio system in the car, so they purchase a head unit and components that meet increased requirements. In this case, the question arises of how to connect the speakers to the radio and whether it can be done with your own hands.

Acoustics device

Component acoustics without an amplifier consists of the following components:

Speakers. The quantity and power of which depends on the specific model;
Crossover, that is, a filter for matching the output impedance of the radio amplifier and for supplying sound waves of the required frequency to the corresponding emitter (speaker). It consists of carefully selected capacitors that act as capacitors and coils to create inductance. Once assembled, an electrical circuit is obtained that acts as a limiter, allowing only the corresponding sound waves to pass through.

This kind of filter is an integral part of any component speaker system. In this case, the shape of the speakers themselves can be any:

round;
oval;
rectangular, etc.

The sound does not depend on the shape of the speaker head; it is based on other factors such as the quality of the diaphragm and its material, as well as professional assembly.

Which ones are better to put

The choice of speakers for a car radio should take into account the needs of the car owner. There are several options. The appropriate location of the device will depend on the size and type (for example, it is better to place speakers in the door or on the back shelf).

Home speakers. Such devices must be connected to the dashboard via a digital input.
Portable speaker. It is most often connected via Bluetooth.
Powerful acoustic speakers for cars. For demanding audiophiles, these are the best speakers that provide spacious, clear sound.

How to strengthen

During installation, it is necessary to carefully strengthen the speakers, since the sound quality and duration of operation of the device directly depends on this.

Coaxial or component

Choosing the right speakers is not that easy. There are currently two types of car speakers in use: coaxial and component. Coaxial speakers include several speakers at once, the so-called strips. There are two-, three- and even four-way speakers. Component speakers are designed to reproduce only a certain segment of frequencies: low, high or medium.

Let’s make a reservation right away that the price tag between coaxial and component speakers varies very, very much; component speakers belong to HI-FI and HI-END equipment and are expensive, and also require a professional amplifier (possibly more than one) and competent installation. Moreover, the location of such speakers in the car is of no small importance for the overall sound quality.

Where and how to install

Before you begin, you should select a suitable installation location. Some car models have niches for placing speakers. This fact makes the task easier. If the location for the speakers is not prepared by the manufacturer, then you need to choose it yourself.

Are you a car driver?! Then you can take this simple test and find out. Go to test »

It is recommended to install the front pair of speakers in the car on the outermost sections of the dashboard. Another suitable option is the front door housing. In this case, not only high sound quality is achieved, but also the most reliable fixation of the device. To install speakers in doors, measure the diameter of the speaker and cut a hole for it in the door trim.

The rear pair of speakers is most often placed on the floor in the luggage compartment. However, it will require some work to achieve good sound. The standard trunk shelf is removed, and an acoustic podium with speakers is installed in its place.

Main selection criteria

When choosing and purchasing component acoustics, you should focus your attention on the following parameters:

Dimensions suitable for the installation space;
Power. You cannot install acoustics whose power is less than the final amplifier of the radio;
Active resistance, there are two options: 4 or 8 Ohms, this indicator must be consistent with the equipment reproducing sound;
Operating frequency range and number of components.

The price of a particular kit depends on several factors:

brand awareness;
technical characteristics;
quality of materials and components;
acoustics class;

In addition to the listed criteria, each acoustics manufacturer has individual sound characteristics, which also need to be taken into account in accordance with the preferences of a particular music lover who is selecting equipment.

You need to know what load the amplifier is designed for: usually it is 4, 8 or 16 ohms.

It is possible to increase the load (the resistance will increase - the volume will be lower), but decreasing it is risky, the amplifier may burn out.

That is, you can connect all the speakers in series without risk; in extreme cases, you will lose volume. But if we proceed from the load for which the amplifier is designed, then we will have to calculate what kind of connection you will need.

Basic formulas for calculations for serial and parallel connections:

Sequential: R = R1 + R2 + . +Rn; Parallel: R = (R1 * R2 * . * Rn) / (R1 + R2 + . + Rn);

vitas.kg You have a parallel connection of speakers with a resistance of 4 Ohms and 4 Ohms.

The load resistance with this connection is:

R = (4 * 4) / (4 + 4) = 16 / 8 = 2 ohms;

See amplifier specifications or output labeling.

As I understand it, you can connect at least as many speakers in series, as long as they have the same resistance (Ohm)?

serial connection is like this:

Parallel is like this:

janson Ha-ha, but it wasn’t the king’s business that he said, but himself.

vitas.kg Judging by the fact that by connecting 2 speakers in parallel and plugging them into the amplifier, you did not burn it, the amplifier is holding 2 ohms. But this is the limit; standard amplifiers at a nominal 2 ohms usually do not. Then you better hook up all 4 speakers according to the scheme of 2 groups of 2 series-connected speakers in parallel. This results in a total output of 4 ohms. In general, from 4 speakers of 4 ohms you can only get 1 ohm, 4 ohms, 16 ohms - that's all. Yes, judging by the picture, you are familiar with the fact that phasing must be observed. Just in case, if the marking is erased, the method for determining the phasing is to briefly attach the battery to the speaker; if the emitter has gone forward, you hooked the plus batteries to the plus of the speaker; if backwards, you hooked the batteries to the plus minus the speaker.

And now the most important thing. Column box design. This is what determines almost 80% of the sound quality, and not at all the quality of the speakers. And for the correct design you need to know the brand of the speaker. Scratch, look, if you don’t find it, take a photo, you can tell by its appearance, and just to be sure, write down the diameter of the speaker.

HardNik2 Thank you, my amplifier is homemade. Dad has been collecting it for a long time, but he doesn’t remember how much he pulls out. I just connected one speaker to it, and connected 2 speakers in parallel, and in short, I connected everything in a row, both 4-ohm and 8-ohm speakers. Works. In general, I found a bunch of old Soviet speakers at home, there are different ones, 1Gd, 2Gd, 3Gd, 0.5Gd, and their resistance is also different.. And 4 Ohms and 8 Ohms.. And I connected each speaker through this amplifier and checked. Those that didn't sound very good were thrown out.

vitas.kg Aha, that's what I thought - 4 ohms are most likely old Soviet paper ones. And now I’ll tell you a big, big secret - carefully assemble these same 3GDs (or with the later marking 5GDSH) and blow off the dust from them - these are the most super-duper audiophile heads, although they used to be in every Soviet tube TV. But they are fully revealed only on a tube amplifier. And a group emitter from them - oh, this will be something, on any amplifier, from such speakers, installing them in a column of 10 pairs (20 pieces in total), dipole emitters are built. From 4 nominal speakers you can easily squeeze out 20W, with negligible distortion, but there are guitarists who have been using such a combination for many years with 50W amplifiers, and, you know, they always turn it to the maximum - the heads don’t burn, don’t jam, gentle clipping even on a transistorless transformer amplifier.

If you need a body for them, I will order a batch for cutting at the end of the week. True, in my columns at the top there are an extra 15 cm from the calculated ones, which is even better for the OY. Dimensions 530x700x250, design - Group Emitter in an Open Box. At the top is a place for a guitar tube amplifier.

In short, I collected all the speakers that were there and took a photo (on my phone, so sorry about the quality). Here's what I have:

Almost all speakers are like this: I want to make a column out of them:

There are also 2 speakers that are just as big as the first ones.

Here's one:

And here is a general photo of the speakers, not including the two large ones:

Now I’m thinking, which ones would be best for me to make a column from?

If there is one speaker, then you can do this: One pair in the last (those that are the largest), the second pair in the last (any 2 speakers out of 4). They are in parallel with each other. A couple of tweeters (those on top in the middle) through the air conditioner and in parallel to the existing ones. The husband should combine the tweeters into the afterbirth. And the flair and power will be more or less good. It’s just better to separate the two pairs by volume from each other.

vitas.kg Drawing for a column of 2 large speakers in the links I provided. Slavik gbkjn In the 3rd photo - 4gd38, there are 2 of them, in the photo below they are not included. Band 63-12500 according to honest Soviet 3 dB, according to the bourgeoisie it will be beyond 16 kHz, resonance 60, this is a broadband miracle, nothing else is needed. A condenser in a bandpass filter and connecting different types of speakers will completely kill the sensitivity of paper and light suspensions, will give rise to a bunch of nonlinearities in the frequency response (who said that the impedance of bandpass speakers is linear in power, L speaker coils are not a linear system in principle, therefore a bandpass filter without a good inductance is crap). Here is a separate HF satellite, as you practically suggested - it’s a good thing, but it needs to be hung on a separate channel, and set with ears (and I don’t have them, you’ll have to use a sharpening rod with an error) to set it. So this is not the case. Do you agree?

And then I just now made a monster with 4 of these with replaced caps - an OYA cabinet 860x860x400 (only materials cost 2000 som - 30 MDF) (practically this is an Acoustic Screen for the dropD system, mitollugs should shit with happiness), a 50W lamp on EL34. Maybe I was wrong, and I should have destroyed one 4A28 after all?

PS By the way, AD 8066 arrived after 4 months, send me your phone number in a personal message if you still need it.

How many EL34s are there in the amp? What is the gain class? Judging by the high power: "B".

PS By the way, AD 8066 arrived after 4 months, send me your phone number in a personal message if you still need it.

this is called tri-mode, each channel has its own speaker, and the third is a bridge on them. the third one will just play L+R, but to equalize the volume (in the matrix model the center should be -3 dB relative to L and R), you will have to hang up the rezyuk for sweating to dampen excess power, while all the excess goes into the heat

Wiring issue

When installing wiring, there are several important rules to consider.

If there are no specialized holes in the doors for pulling wires through, you will have to drill them yourself.
The wire should not pass through metal and plastic without protection. For safety reasons, it is recommended to use spacer rings. They are fixed on the inside and prevent contact of the wiring with the casing.
The cable to the head unit should be laid under the interior trim. The best option is to secure the cable from the speakers to the main wiring using electrical tape.

Wire marking

Most speaker systems are equipped with a set of cables that have colored insulation. Thus, FR (front right speaker) is marked in gray, FL (front left speaker) is marked in white. The wires for the rear speakers are similarly different. For the right rear (RR) use purple insulation, for the left (RL) - green. The cable on “-” has the same insulation color as on “+”, but is supplemented with a black stripe.

If the wires for connecting the speakers have all the insulation in the same color, the cable must be marked. This will allow you to connect the speakers to the radio in your car quickly and correctly.

I am the Master Receiver

Previously, all over the world there were pictures like how to connect acoustics and a sub to 2 channels; the acoustics were not cut from below, the sub was cut just a little and very high with a large throttle. but in the 90s it worked (especially in cans, when 6x9 in the rear parcel shelf and a sub in the trunk)

Andreich, your option (the price of the experiment is two wires):

So I was waiting for someone to tell me about this option! I kind of knew about it, but I didn’t know how to dull the one with the bridge!

Any guesses about the resistor value? If we are talking about 4-ohm horns with sensitivity above one hundred?

I am the Master Receiver

take 20W 4.7ohm, 5.1ohm and 5.6ohm - choose the one you want

Every car enthusiast who values high-quality sound should know the basics of installing an audio system. Today, not all cars are equipped with radios, so drivers have to install the speakers themselves. How to connect speakers to a car radio, how to position the speakers correctly and what you need to know about wire insulation - read below.

Connection diagram

After the cables have been laid and labeled (if necessary), you should proceed to connecting the acoustics to the head unit. To connect the speakers to the car radio, make sure that there is no short circuit to the body. To do this, check the wiring using a multimeter.

The next step is to check the impedance of the speakers themselves. The norm is 4 ohms. If there are no discrepancies with these parameters, you can begin connecting the cable. Each receiver should include a circuit diagram, so installation will not take much time.

The easiest way to connect the speakers to the radio in your car is using ISO connectors. If they are not provided in the standard radio, you can purchase a separate ISO adapter. With its help, you can quickly replace devices in the future.

Front

If the wires have multi-colored insulation, connecting them will be easy. The front speakers have light-colored cables:

If there are no markings, you can check the speakers as follows. A finger battery (AA or AAA) is connected to each wire for a short time. The speaker connected to this wire will begin to make a squeaking sound. This will allow you to connect the front speakers correctly.

You can also use a battery to identify plus and minus.

When the diffuser moves upward, positive polarity can be determined.

Rear

When connecting the speakers to the radio, you need to remember: the rear speaker cables have dark insulation:

purple (for the right device);
green (for the left).

If markings are not provided, you can, as in the case of the front pair, check by connecting to a AA battery. Each wire must be correctly connected from the speakers to the head unit into the connector provided for this purpose. After this, the connection of the rear speakers to the radio can be considered complete.

Home speakers

Some car owners are wondering how to install pop or household speakers from a music center. Theoretically, such a connection of speakers is possible, but there are a number of nuances.

The quality of the sound produced will be lower than with car speakers. This is explained by the fact that household speakers are designed for use in open spaces.
The voltage on these devices is different from the voltage on car devices, so a conversion will be required.

With an active system on the power supply board, it is necessary to find the points at which voltage is supplied to the amplifier. In these places the device is powered by a battery. As for the connection diagram to the head unit, it can be different:

directly from the radio;
through a power amplifier.

Amplifier

Connecting an amplifier will increase the volume and sound quality. A cable from the head unit and a power wire (it comes from the battery) are connected to the amplifier. The next step is connecting the speakers. When using a bridge circuit, one channel is connected to “-”, the other to the load terminal “+”.

How to connect 6 speakers

Experts emphasize the fact that the sound quality in a car largely depends on the power and capabilities of the speakers in the car, and not on their quantity. Meanwhile, many car enthusiasts are wondering whether it is possible to connect 3 or 4 pairs of speakers to the radio.

To solve this problem you will need to purchase an amplifier with 4 outputs.

Portable speaker

Instead of a radio, you can use a portable speaker that connects to a smartphone or any other gadget via Bluetooth. This device is widely used among car owners. The list of its advantages includes a relatively low cost, no need to connect to the car system, and the ability to use it not only in the car, but also in any other place.

The only drawback of a portable speaker is that the sound quality often does not reach the level of specialized speaker systems consisting of an amplifier, speakers and subwoofers.

Number of speakers in the car

Should you put 2 speakers or 4 speakers in your car, or maybe 6? The purity of sound is determined by the quality of the speakers, not their quantity. Many car owners are limited to two mid-frequency component speakers in the front doors and tweeters on the pillars, while a subwoofer is placed in the back, which plays low frequencies. Thus, the entire spectrum of sound in the car is revealed.

Also popular is the option of installing 4 coaxial speakers, 2-3 way in the front doors, 3-4 way in the rear parcel shelf. The number of speakers that can be installed is limited only by the size of the car and the desire of its owner. At various car audio competitions you can see cars with dozens of speakers installed throughout the car. 2 speakers in the front doors may well be enough for you, it all depends on your musical preferences.

Connection

When replacing speakers or installing new ones, pay attention to the quality and condition of the wiring. Thin wires with twisted connections are not capable of transmitting sound efficiently and without loss. There is special wiring for transmitting the audio signal - it is a multi-core copper or silver shielded cable.

For clear and high-quality sound, installation of such wiring is necessary. Pulling new wires to replace the old ones is quite simple; tie a new cable to the end of the old wiring and carefully pull it through the other end of the wire. During the connection process, it is very important not to confuse the polarity; the wide terminal on the speaker is the positive contact.

When connecting speakers through an amplifier, the wiring from the radio is stretched to the location of the amplifier, and from it diverges to the speakers. The amplifier's power wires should not be pulled together with the audio wiring; it is advisable to space them away from each other, this way you can avoid interference from pickup. The amplifier heats up during operation; free space is required for its normal cooling.

It is important not to forget to connect the audio system through a fuse, the power of which is calculated using the formula “Output power / 12 volts = number of amps of the fuse.” For example, 4 speakers are installed, 40 W each /12 = 13.3, we install a 15A fuse.

For some reason I always thought that the power and purity of sound depended on the number of speakers in the car, it turns out. it all depends on the quality. And I didn’t think about the quality of the wiring at all. Now I know.

It turns out that you can find information about everything on the Internet. In short, I went to connect the speakers to the radio, but I thought that for such a “teapot” like me, this mission is impossible) Anything is possible!

I also had to install speakers in my car. Only specialists did the installation, since I don’t understand anything about it. I have many speakers throughout the cabin and the sound quality is excellent. If you wish, you can learn how to install it yourself by reading this article.

Damn, after reading the article I really believed that the sound could be made better. My husband proved it to me, but I didn’t believe it. I bought new speakers on Avito, I was still cursing why, although now I think it’s no big deal, it’s still cheaper than in regular stores. In short, it will change, I have one more review)

What you will need

To install speakers to a car radio, you will need the following list of tools and items to interact with them:

Pliers and other tools for cutting off unnecessary elements of insulation and everything connected with it. You can use scissors, but they will quickly become unusable.
Before installing speakers, buy special cables as backup. Depending on the type of speakers, these cables will connect the device interfaces. So, for example, for simple speakers from a music center, wires with a minijack interface are connected. As for everything else, you need to look at the situation, since the equipment may be different.
You will need to get the speakers themselves, taking them out of the music center and turning them into speakers for the car radio. They connect through interfaces. These interfaces are mini jack, tulip or HDMI. The latter is used in advanced professional devices.
It is worth taking a closer look at several test audio recordings so that you can quickly and quickly check the performance of certain devices if you connect them to the receiver.

Pioneer DEN MVH-150UB

Basically, connecting the Pioneer DEN tape recorder is similar to the standard algorithm. MVH-150UB is a device adapted to any car that has a landing pocket.

Pioneer DEN has the same settings. The only difference here is in appearance - in the shade of the backlight. You can see the difference in the photo. Settings are saved even if the battery is disconnected. There is a connector for connecting a regular phone or Android.

Radio tape recorder Pioneer 150UB

Every car radio comes with instructions. In it you will find detailed information, photos and a diagram without mistakenly connecting the sound system. And with the right approach, connecting the car radio can be easily done independently.

Also included are two steel plates with eyelets. These are special devices that make it possible to remove the tape recorder from your pocket if necessary. The plates are mounted to the sides of the tape recorder. The lugs are bent with a screwdriver and the panel is closed.
