Subwoofer output one tulip

More precisely, the connection diagram of the MYSTERY MSK-12 subwoofer kit to the MYSTERY MDD-6270NV radio (head unit).

I’m not a fan or an ardent admirer of MYSTERY, but it so happened that I bought MYSTERY by accident; at that time I was not interested in the manufacturer, but in the fact that it had navigation, and all this was relatively cheap. And I got the sub kit from my uncle, for which I thank him very much.

So what do we have and what needs to be connected.

consisting of a low-frequency speaker (subwoofer)

and 2-channel amplifier

all this needs to be connected to the GU

having these RCA outputs (SUB/FRONT/REAR, there are also video outputs, but we are not interested in them now.)

Sub out (RCA)

I don’t know why, but for some reason the manufacturer decided to make the sub output with one tulip, and not two (as is often the case). Faced with this problem, I decided to consult with the seller (a well-known VEGA store in Perm). To which the seller told me, given that there is only one way out - you need to install a splitter.

That is, we take a classic interconnect RCA cable 5 m long and use only one of the 2 wires and connect it to the splitter

the black tulip will hang out, maybe if I change the GU and there will be 2 outputs for the sub, it will come in handy.

Thus, what goes with the splitter goes to the amplifier

and the second end to the dark green tulip GU (SUB output). All interconnections are completed.

Next are the power cables. I read in the instructions for the harness that the power wires should be 4Ga. And in stores this MSK-12 subwoofer kit includes wires with a cross-section of 6mm^2. Although the cross-section of 4Ga should be 21.2 mm^2. Already the manufacturer has discrepancies in instructions and production! In the same store, the same seller showed me that a 4Ga wire costs 330r/m. But I need 6 m (5 for + and 1 for -), to put it mildly, I was not ready to pay 1950 rubles for 6 meters of good wire. To which the seller offered me a more budget-friendly option.

In the photo, I think you can see the list, the power section of 9mm^2 is of course not 21 mm^2, but it’s better than 6 mm^2

Well, here it’s already clear and just 5 m of red, we end one end with a ring terminal and put it on heat shrink (included in the kit) and hook it to the battery (+). After 30 cm into the gap we install a 30A fuse with a housing (also included in the kit).

We also terminate the other end of the red cable with a Y-shaped terminal and hook it to the amplifier at (+)

Types of low-frequency audio speakers

A subwoofer is a sound speaker designed to reproduce improved quality of low frequencies that are not available to conventional audio speakers of standard car equipment. Subwoofers are divided according to their types:

The active subwoofer comes with a built-in power amplifier to remove low frequency loads from the main car audio amplifier. And also, its own crossover (a device for dividing frequencies into high, mid, low, etc.), which simplifies the coordination of the subwoofer with the acoustics of the standard radio.

A passive subwoofer does not have a separate (personal) power amplifier and is connected to standard speakers. Which, as a result, negatively affects the sound quality of the car's stereo system and causes additional overload on all output channels. As a result of this, the volume and dynamics of the sound decrease.

What is the functionality of the radio?

The fact that there is a standard radio in the domestic car Lada Granta Lux and in Kalina-2, and the devices are constantly being improved. A special feature of the radio is that it fits deep into the standard place, which is accompanied by minor difficulties when removing it. The large monochrome display displays a user-friendly interface.

Instructions for connecting the Mystery passive subwoofer to the Pioneer radio

The schematic diagram of low-frequency speakers of both active and passive types is almost the same, with the exception of small additions related to non-active subwoofers.

For this reason, we will analyze the general method and then make changes.

The process of turning on a car radio with a passive subwoofer is very simple: it is connected directly to the amplifier, which, in turn, is connected in series to the car player.

The role of the standard amplifier in this circuit is to transmit the signal received from the sound of the playback device (car radio) to speakers with high and low resolution frequencies. Where the subwoofer itself acts as a converter of low-frequency signals, and its satellites act as a converter of high-frequency signals.

Due to its rather large dimensions, the installation of the subwoofer is carried out mainly in the luggage compartment of the car and the power supply wires have to be pulled through the entire cabin to the battery. Which does not improve its (interior) appearance.

Not active subwoofer

You can connect a passive subwoofer to a radio without an amplifier in 4 steps.

Through the technological hole in the engine compartment we stretch the supply wire to the battery. We install a fuse on the positive (plus) wire closer to the battery.
We pull the wiring into the cabin and stretch it to the trunk, if possible disguising it under the interior trim parts.
We insert the wires through the finished technical hole (if necessary, we make it ourselves) into the trunk of the car. And we connect directly to the low-frequency speaker, according to the diagram (+ to +, - to -).

Removing the radio on Grant

The entire dismantling process will take no more than one minute if you have already removed the radio before. If this is the first time for you, then minor difficulties may arise only with finding the necessary elements by touch if the radio is not pulled out in the usual way.

Procedure:

1. Remove the plastic trim of the center console. To dismantle the MMC, it is not even necessary to remove the cover completely; it is enough to unclip only the upper latches using a screwdriver, a small knife or a spatula.

2. Slightly pulling back the upper part of the plastic trim of the center console, press out the MMC latches, which are located on the right and left. To prevent the latches from “settling” into place, you need to slightly pull the MMC towards you.

3. Having released the clamps, we remove the MMC from the niche.

What to do if the wires interfere with the removal of MMC?

If the cables going to the MMC block prevent you from pulling it out, then you need to disconnect them. To do this, just do the following:

1. Lower the glove compartment lid down and disengage the upper latches.

2. Stick your hand into the opening and disconnect the interfering cables

Please note that not all MMCs currently have a USB cable installed that goes into the glove compartment

The radio has been dismantled, now you can connect additional equipment to it, replace it with another one, or simply find out the model of your MMC by the sticker located on the rear panel.

How to Connect a Passive Subwoofer Without an Amplifier

Summary of how to connect a subwoofer to a radio without an amplifier

Before we talk about how to connect a subwoofer to a Pioneer radio without an amplifier, let’s figure out what a subwoofer is and what types of such acoustic equipment are installed as additional equipment by car owners.

Types of low-frequency audio speakers

A subwoofer is a sound speaker made to reproduce the improved properties of low frequencies that are not available to ordinary audio speakers of standard car equipment. Subwoofers are divided according to their types:

The active subwoofer has a built-in amplifier to remove low-frequency loads from the main amplifier of the car acoustics. Also, its own crossover (a device for dividing frequencies into high, mid, low, etc.), which simplifies the coordination of the subwoofer with the acoustics of the standard radio.

Connecting the sub: important points and instructions

Let's look at the process of installing a subwoofer in a car with a connection to the standard radio. Before starting work, pay attention to a few points:

The subwoofer housing and the amplifier itself are large devices. We need to think about where to place them. Most often, a place is allocated for them in the luggage compartment of a car.

If possible, the amplifier is placed on the back of the rear sofa. Remember that the amplifier and active subwoofer become hot during operation. These devices require good cooling. Position the amplifier and sub so that air can circulate freely around the devices.

How to connect a subwoofer to the car's on-board network

We will not dwell on the choice of installation location for the subwoofer and the method of its installation. This depends on the car model, the size and shape of the subwoofer, and individual preferences.

First, it’s worth saying a few words about the types of subwoofers and how to connect them. Subwoofers are either passive or active.

A passive sub is a low-frequency speaker that contains one or more speakers, which can be installed with or without a factory box. This subwoofer receives only the audio signal from the amplifier.

The active subwoofer circuit has its own amplifier, so in addition to the signal wire from the radio, you need to connect power to it, the “+” and “-” terminals.

To complete the work you will need the following materials and tools:

wires (we’ll talk about the requirements for them below);
plugs and tips (tulips, etc.);
nippers and pliers;
screwdrivers of the required sizes;
insulating tape;
clamps for tying and fixing wires.

What power wire should I use and how do I connect it to the subwoofer in my car?

Power wires are the power wires of the amplifier - external or built into the subwoofer. That is, no power wires are connected to the passive subwoofer.

The main requirement for a power wire is its cross-section, that is, the thickness of the copper core. The resistance of the wire increases as its cross-section decreases, which causes a significant voltage drop when a large current flows. This leads to a drop in output power, the sub begins to “choke” at peak volumes, and damage to the amplifier or speaker elements may occur. In this case there is no need to talk about the quality of music playback. Below is a table that shows how much power wires can carry through them depending on their cross-section and length.

Wires should be copper, stranded. After purchasing a subwoofer or amplifier, check the quality of the standard wire included in the kit. It can look very beautiful. But in this case, appearance does not play any role. Inspect the conductors at the ends of the cable. If necessary, bite off a small piece of the wire to make sure it is copper and not copper-coated aluminum. Aluminum is a rather brittle metal, prone to oxidation and has a slightly higher resistivity than copper. Change this wire without regret. It’s good if the ends of the wires are already tinned, that is, covered with a layer of tin.

Functionality check

This completes the installation of the radio. It is imperative to diagnose its performance. To do this, all functions and the quality of their operation are checked. If the installation is done correctly, there will be no problems at this stage. At the same time, carefully check whether the buttons on the device work correctly.

If problems are found in operation, you will need to dismantle it again. Since the reason may be hidden in the fact that the connection was made incorrectly. Carry out all work carefully and accurately. Then the device will function efficiently and for a long time.

Setting up a Nissan note radio

Installing a Nissan note radio is an important job, but not complete. After this is completed, you need to configure the multimedia system. So each model has its own code. It must be entered to gain access to device settings and functions.

Finding out the code for your Nissan note radio is easy. It is mainly indicated in the operating instructions. It protects the device from intruders. This information should only be known to the owner of the device, so you should not disclose it to others.

After this code is entered, the device will be unlocked. Then you can configure it. It will take a little time, is simple and clear. If difficulties arise, you can contact specialists who have experience in solving such problems. They will do this work quickly and efficiently. All you have to do is enjoy the process of operation.

It is up to each owner to decide whether to do everything on their own or turn to specialists. He must analyze all the pros and cons of these options. This will help you make the right decision.

One of the most popular models on the market is the Nissan note 2007 radio. This is a modern version of the device. It is reliable, practical, easy to use and durable. At the same time, it is equipped with many functions that are so necessary for the driver.

It is also worth noting that it is easy to install and configure the Nissan note 2007 radio. You can do this work yourself. Thus, you will save money that you could spend on the services of a master.

Connecting an active subwoofer

As we have already said, an active sub combines an amplifier and a passive sub. Connecting such a system is even easier. This is explained by the fact that the amplifier is already connected to a speaker inside the active subwoofer housing. Otherwise, the connection process is no different from the “amplifier - passive subwoofer” system.

When purchasing an active sub, check the standard wires that are included in the kit. They may not meet the requirements for cross-section and material from which they are made. In this case, by replacing them in accordance with the recommendations outlined above, you can significantly improve the quality and volume of playback.

Flaws

You won't be able to play video files on MMC XRAY.
It’s a matter of habit – the radio does not have the round volume controls familiar to all generations of domestic car owners. Only the buttons can increase/decrease the sound.
The volume of the radio can be controlled using the multifunction steering wheel, but you won’t find buttons for switching tracks here; you still have to reach out to the screen.
USB devices are read quickly, but the flash drive must be in FAT 32 format, and the maximum memory capacity cannot be increased beyond 32Gb.
The standard IGO navigation program may begin to slow down when driving. Stutters may occur when entering an address. There is no way to change the map scale with your fingers: control only with buttons.
Navigation map updates are quite expensive, especially since maps in Russia are not of the best quality. Free map updates are performed only once after purchase within three months from the date of device activation.
The lack of line outputs means that connecting an amplifier and subwoofer in one minute will not be possible. You will have to solder the line outputs or connect the amplifier and subwoofer to the rear speakers.

Of the biggest drawbacks - the inability to play video, there is a decent solution. Firmware will help solve all these problems.

In general, it is clear that the XRAY MMC leaves only pleasant impressions with its functionality; there are shortcomings, but they are not particularly significant. The price of a multimedia system for a domestic car is quite unexpected, but if you compare it with the cost of multimedia in some other foreign cars, it begins to look in a different light.
