How to connect and configure a mystery subwoofer

Active subwoofer Mystery

This article can tell you how to connect a Mystery active subwoofer. The main advantage of this technology is its price. In addition, this sub can be easily connected to the radio, after which it can be placed in the car interior. By the way, such a speaker is usually placed directly under the car seat. The connection diagram for the Mystery active subwoofer implies reproduction of frequencies in the range of 30-200 Hz.

What do you need

Before you start connecting the Mystery subwoofer, you need to find or buy several additional components in specialized stores. They will be used during work and will allow you to achieve the desired result as quickly as possible.

To connect the Mystery sub you will need the following components:

• control wire;
• fuse for power wire;
• amplifier plug;
• 2 power wires;
• reversible RCA cables.

In addition to various components, you will need some materials and tools for the job. Without them, it will be impossible to do quality work.

List of required items:

• screwdriver;
• pliers or pliers;
• knife;

Opinion of our store experts about Mystery MBB-252A: Mystery car subwoofers are relatively inexpensive, but they sound bad, the actual power is lower than declared, it is better to buy a more worthy option.

Easy way to connect

Connecting the Mystery active subwoofer is done in two main ways. One of them is suitable for beginners, and the other is for professionals. When choosing the best option, you should evaluate your own capabilities, as well as your ability to perform such work.

Subwoofer connection procedure:

1. A place is found in the car interior where the device will be located. Experts recommend placing the subwoofer so that passengers sitting next to you do not experience inconvenience from the loud sound emanating. However, it is prohibited to install the equipment in places where it will be obscured by any object. Otherwise, the sound quality of the melodies will decrease.
2. Using power cables, connect the subwoofer to a power source (battery). If it is not possible to use this option, then connect the device through the cigarette lighter.
3. A fuse is installed on the positive wire. This is necessary to ensure that a sudden surge in voltage does not damage the elements of the audio system and render it inoperable.
4. The connected subwoofer is connected to the radio using double-sided RCA cables (“tulips”).

Universal remote control

Pay attention to a universal push-button device from Huayu, Dexp or another brand - this is another option for solving the problem with the remote control. The fundamental difference between such devices is the ability to process several types of signals, which ensures compatibility of universal remote controls for TVs from different manufacturers

The advantages of universal remote controls are the following:

1. Compatible with over 1000 TV models. Suitable for any TV.
2. The range of action is as wide as possible - 10-15 meters.
3. Can be used to control other types of equipment.
4. It is easy to set up to work with a specific device, just strictly follow the manufacturer’s instructions. To configure a universal device, special codes are used, which differ for different TV receivers. The necessary information is provided in the operating instructions for the device.
5. The price is affordable, significantly lower than the original remote controls of popular brands.

When choosing a universal remote control, it is recommended to pay attention to the following important characteristics:

• presence of a training mode;
• interaction radius;
• design and ease of use;
• price.

Connection via amplifier

Having understood how to connect the Mystery active subwoofer, you can perform a similar operation with a passive device. This type of work involves the use of a special amplifier, which is connected to the subwoofer. Thanks to this additional element, the volume limit will increase and the sound quality will improve.

1. One end of the negative wire is connected to the GND terminal on the amplifier.
2. The opposite edge of the same power cable is connected to any part of the car body.
3. Contact points are carefully isolated.
4. The positive wire is connected to terminal +12 located on the rear panel of the amplifier.
5. A fuse is installed on the power cable.
6. Find the Remote terminal on the amplifier and connect the subwoofer to it.
7. Using an RCA cable, connect the amplification device to the radio.
8. Check the reliability of the connection and begin setting up the acoustic equipment.
9. To do this, insert a disc into it (included in the Mystery subwoofer kit) on which a test melody is recorded.
10. After the sound starts, turn the volume down to minimum and begin adjusting the settings.
11. As soon as the sound becomes “clear,” increase the volume and retest the device.

Setup instructions

To listen to music in good quality, after purchasing a subwoofer, you need to know how to install and how to properly configure the amplifier in the car. First, it should be connected to the amplifier, and then all settings on the head unit (GU) should be set to zero. The following is a step-by-step implementation of adjustment actions (aviacopTube).

Stage 1

First of all, the filter designated LPF (low pass filter) should be turned on on the amplifier or PG. Thanks to this filter, only low frequencies are sent to the speaker. The most popular frequency is in the range of 50-70 Hz. Enabling this filter prevents the appearance of infrasound, which can damage the device. Having set the frequency, it needs to be adjusted. Moreover, if there is an LPF filter on the GU, then it is better to configure it on it. Otherwise, make adjustments on the amplifier.

Enabling the LPF Filter

Stage 2

At this point, the filter is set to HPF to adjust the high frequencies. The cutoff is set in the range from 70 to 90 Hz. When using passive division, filter adjustments end here. If local amplification is involved, the tweeters will need to be configured. To do this, the channel filter for each tweeter is set to the HPF position, while the cutoff frequency of the subwoofer should be approximately 2.5 kHz.

Stage 3

An important step is to adjust the sensitivity level. It is designated by the words GAIN or LEVEL. This function is used to match the sensitivity level of the amplifier and the GU.

First of all, the maximum volume is set on the GU. The settings on the amplifier should be set to zero. Next, the sensitivity regulator should be turned towards increase. If distorted sounds appear, you need to turn the control back a little.

Adjusting sensitivity on the amplifier

Stage 4

This step involves adjusting the sound quality. If, when you turn on the speaker system, clicking sounds appear in the subwoofer, it means that there is some interference with the signal. In this case, you need to check where the wires are laid and, if necessary, run them in a different place.

If the subwoofer is set up correctly, bass should not appear in the rear of the cabin. If this is not the case, you need to connect the device in the opposite phase to the amplifier. To do this, turn the phase control on the device 180 degrees. If there is no regulator, then you need to connect the positive wire in place of the negative one, and the negative wire in place of the positive one.

If there is a processor on the head unit, you need to do the following:

1. In the case where a note was played in the front speakers, and a split second later it was heard on the sub, time delays occur. To avoid this, you need to adjust the delays on each amplifier channel. This way, the front speakers and subwoofer will play simultaneously.
2. In order for the driver to hear music well from both the left and right speakers, you need to set a time delay on the left channel.

Next you need to turn off the subwoofer and start music. With the subwoofer turned off, you need to adjust the volume, frequencies, and equalizer so that the speakers in front and behind at maximum volume sound without distortion

It is important that the track plays correctly. If distortion appears, you should turn the volume down and remember the place where the lowest sound was in the work

The last test check concerns the bass. You need to turn on the music and listen to the bass. If you don't like the sound, the bass can be adjusted with a bassbutton. If there is a delay, turn the PHASE control until the desired sound frequency is obtained.

Advantages and disadvantages

How to connect an active Mystery subwoofer

The most important advantages of this active subwoofer are the following functions:

• It is equipped with a built-in amplifier, due to which an even higher sound level is achieved.
• This device is very compact in size.

Note. Due to this, it can be easily placed, as mentioned above, directly under the car seat.

• Thanks to the quality characteristics of this speaker, it is possible to reproduce sound with clear low frequencies. At the same time, due to this, the frequency of the sound will be slightly increased, which is why it will be clearer.
• The speaker costs very little - only 2500 rubles. But despite the price, it is very reliable.
• Its sale began in the Russian Federation in 2012. That is why purchasing such a device will not be difficult, since it is now quite common.
• And although the device has a very compact size, the sound quality can be called very good. That is, the subwoofer (see How to make a subwoofer: practical tips) has excellent sound output.

How to connect an active subwoofer Mystery

• It has a stylish design (although this is not so important, because it will still have to be “hidden” under the seat). However, due to this, it can be placed near the rear window without any problems. But in no case will it affect the overall style of the car. The body is aluminum and very durable. As a matter of fact, you can be convinced of this only once you see this speaker.

Note. The speaker can easily withstand even the strongest mechanical shocks. And this is a fairly common occurrence, since the device is located directly under the car seat.

• The remote control of any system perfectly controls the volume of the subwoofer. Also on its body there are several additional adjustments that facilitate the operation of the subwoofer itself.

Remote control that fits directly on the steering wheel

• The sub has an overload and power-on indicator, thanks to which the user can always understand whether the device has already booted up or whether it needs to wait a little longer.
• Suitable for any car as the speaker is universal.
• It is easy to connect, but this requires special knowledge.

Note. You can get them after reading our instructions.

This device has few disadvantages. But still they exist:

• Connecting a subwoofer is specific, so you will have to tinker with it a lot.

Note. You should not purchase this subwoofer based solely on its price. This technique is perfect for those who are installing a subwoofer themselves for the first time. It will fit into a car that requires not too high acoustic parameters.

Mystery sub MBB

• Has a small size. At the same time, it also weighs very little.
• It's cheap.

Connection

Mystery active subwoofer how to connect

Connection can be made in several basic ways. Moreover, each of them is original.

Connection according to low level of knowledge

Mystery active subwoofer connection diagram

In this case, the connection itself is made by connecting the linear input of a special amplifier (see How to connect an amplifier and a subwoofer to a car radio: you are your own master) to the subwoofer input. This input is called “stereo”. Once connected, inside the amplifier these signals are either mixed or transferred to 2 different amplifiers.

Note. If the amplifier has only one connector, then the receiver is connected using a cable to the line inputs located on the subwoofer. In this case, you have to follow the instructions that are usually included in the kit.

High level connection

• The speaker inputs of the device are connected to the amplifier input. In this case, you cannot touch the built-in amplifier. Both outputs coming from the amplifier's speakers are connected respectively to the outputs available on the device itself. Speaker inputs have special terminals, which make switching easy and simple.

How to connect a Mystery subwoofer at home

This is the situation.
The other day we picked up a Mystery mbv-301a sub, so you can get it for free . but there are no freebies in Russia. so it is in my case. There is a sub, but there are no instructions or wires for it.

So, I would like to find a complete set of wires, where they could be purchased, their price and, accordingly, instructions for installing the subwoofer.

Who will explain in their fingers what to put where, where to turn on and how best to lay the cable. to that Magarych in the form of a bottle of cognac or 10 liters of live beer (artel))) with delivery)))

in any electronics hypermarket. 1 interconnect cable (I have it lying around in the trunk if you need anything) + 2 power cable (thick red) + 3 fuse box + 4 ground wire (usually brown) + 5 control wire

everything costs no more than 1 thousand rubles. (a case of you)

1 connect to the subwoofer output of the radio (if not, then to the “rear” linear output) and pull along the right threshold 2 to the battery and to +12V on the amplifier 3 to 2 (i.e. to the power cable) but no further than 30 cm from battery 4 to ground on the amplifier “ground” and to the body somewhere in the trunk (just so that the contact is good) 5 to the blue wire on the tape recorder (to which the active antenna is connected) and to “remote on the amplifier”

2 and 5 you pull along the left threshold

Here's the first trouble

. on the right side, where under the inscription Power rem, the input is apparently for power, that’s where to find such a connector and where it is connected. I went to Autolife, they didn’t really explain it, they said that *** where you can find it, I went to the radio electronics department on Koltsovskaya, there is something similar there, but there are 8, 4 channel connectors, now I need to find a smart electronics engineer who would fit the whole thing and make it work. there are such?!

second question on the left: 4-channel high input, where is it and where can I find it?!

and the third is remote. where and where to find it?!

I found a wiring diagram. who could help solder this whole thing?!

If there are no wires in the kit, then at least look for a chip that plugs into the sub itself, it has 6 connectors, you buy ordinary mystery acoustic wires, in my opinion they cost about 700 rubles, take a thickness of at least 2.08, and solder it to a chip of six connectors

The positive wire goes thick, you split it in front of the chip and solder it to each chip, do the same with the minus, that is, you bifurcate the thick wire at the very end near the subwoofer as shown in the figure. and Control there can be a thin wire to the radio on the blue wire, this is control of the power supply of the amplifier, if you don’t install it, your amplifier together with the radio will not turn off, it will constantly work and drain the battery (battery)

,Power is similar to powering a video card, only some of the contacts, which are square, are mixed up in some places. and vice versa, adapters are sold “2x4 PIN -> 6 PIN”, I don’t think it will cost more than 100 rubles https://www.avforums.com/forums/attac. olex_pci-e.jpg

and high input, in turn, is similar to additional power supply to the processor from the power supply) only it is not needed if you will connect it through tulips

Mystery MBV-251A reviews

Not heavy. Compact. Cheap.

I’ve been using it since March 10, and I can’t say anything bad about it.

The bass is quite decent. Of course, it doesn’t match MB-Quart, but it costs completely different money. The main thing is that the music sounded correctly at low volume. This sub is not for those who rock the street and anger their neighbors. He is especially good at voicing pop music. Rock, not really.

PriceComponentsSound quality for the price

Dimensions and weight, although for whom is this even +

I bought it for the classics and it strums great. At maximum bass and 30% overall sound in the radio - even the driver is shaking, I’m not talking about the sensations of the passengers in the rear seats - everyone will run away in 20 minutes. I'm pleased with the bass control remote, because it finds bass everywhere even where it shouldn't be - for example, in orchestral or instrumental recordings, but thanks to the remote control you can easily remove it. The package is excellent, there are even harnesses and clamps for wires, but I bought thicker and longer ones separately. The connection is simple - it’s difficult to confuse something.

Price/quality and that says it all. The workmanship is excellent, metal protection for the subwoofer speaker, carpet covering - everything is excellent. The connection is intuitive despite the large number of wires. If you have a linear output on the radio, then you don’t have to worry at all. I was pleased with the remote control of the bass. All I can say about the sound itself is that you should take the time to set it up. The sub is good for the money. VAZ 21099 rocks.

None have been identified as such.

— Price — Size — The power is quite sufficient for a car, at full capacity it’s even too much (your head starts to hurt) — No need to bother with the amp — There is a power control knob that can be brought into the car interior (long cord included)

The manufacturer is somehow inconvenient to install in a car with a cooler basin. I'd like to stick the name on it :)

It was in my first car (Taz 2112) a couple of years ago. I was happy as an elephant, because the price is pennies, installation is not complicated, all wires are included, there is a toggle switch for power control, and there are all sorts of different settings. The amplifier is built in and performs quite well. After a year of use, oddly enough, there were no complaints about the quality - everything worked in both heat and cold at 5+. In short, for those who need extra show-off (2-3 amps and 2000 watts of power in a car for half the cost of a basin) not important, I highly recommend taking it! I myself regret that I didn’t remove my pelvis when I sold it. :(

Reviews about Mystery MBV-251A

Pros: Good subwoofer for the money. If you just need sound inside the car, this subwoofer will be enough. To pump the street, it certainly won’t work.

Disadvantages: Of the shortcomings, I don’t even know what to include here, for the price it’s good for everyone. Wires, sub, amp, everything has been working for 3 years.

Comment: I bought it in March 2014, and it’s almost April 2017, the sub works every day both in winter and summer, the main thing is to hook it up correctly so that there are no extraneous sounds in it. My VAZ 2114 plays very well inside the cabin, that's enough.

Advantages: Price, quality, equipment.

Disadvantages: Not yet identified

Comment: Bought from Citylink for 3440, happy as an elephant to Dr.'s song. dre & Eminem Still DRE couldn't help but laugh out loud, it rocked awesome for a 17 year old Passat B4, it's perfect for those who need nice bass to complete the picture and don't want to install amps and other stuff. will fit perfectly. My parents have an infinity fx 35 with a standard sub, under the spare tire in the trunk, with loud music in the rear view glass there are ripples from vibration, taking this as a standard of cheap but high-quality sound, one can say it is not inferior to a premium car)

Advantages: Excellent bass, beautiful design, bass-reflex body, rich equipment (all wires, clamps included), low price.

Disadvantages: I haven’t identified it yet, except that they would have included fasteners in the kit in order to secure it in the trunk.

Comment: Just an excellent sub for the money, pumped up the car 100%. It's in the trunk of a Nissan Sylphy, it just floods everything in the cabin with low frequencies, it harmonizes very well with the coaxials in the back and the components in the front, highs and mids are audible well, not just dull bass. You need to tinker with the settings, set everything in the radio to 0, started with the sub, raised a little gain, set the LPF to 120 Hz, and added a little bass to all these 3 controls on the rear wall. On the radio, I set LPF to the same frequency as on the sub, added a little SUB +1, LOW at zero, MID + HI at +5, and LOUD mode. Sony Xplоd head. The sub is connected via the linear output from the radio, it’s better to set it this way, the sound is much better, since the input is low-level. The main thing is to set it up so that the bass does not strain your ears and they do not hurt, and then there will be joy. At this minimum power setting it produces good bass. Electronic music, rap, RNB, pop music play great. There’s nothing rattling inside the cabin (perhaps the vibration-thermal insulation is doing its job), outside too, except maybe the rear number plate, but I have it on the clamps)) It’s quite suitable for a sedan, take it, you won’t regret it. And don’t listen at high volume for a long time, otherwise your ears will lose their ability to hear well. Happy shopping and good luck on the roads)

Pros: great sound for reasonable money!

Disadvantages: one drawback, but a very big one! this drawback is PEOPLE who connect the equipment crookedly and then write incorrect comments scaring people!

Comment: excellent sound, simply gorgeous. don't listen to critical reviews! they are written by people who have not set up or connected the remote control, or those who expect that from a sub for 3-4 thousand that it will play like an expensive high-end system. Yes, I don’t argue that the sound naturally doesn’t reach the full ideal and it won’t even be possible to play so much that the car jumps, but it’s 150% worth the money! I installed it in a VAZ 2113 (there is no insulation in the car except for heat, no super cheesy radios and speakers (there are Hertz 16 + tweeter in the back Hertz 6*9 components, there are no amplifiers, etc.)) I turned the radio up to full until the speakers started wheezing but the sub didn’t make a sound that he felt somehow bad or uncomfortable. port an hour and a half to connect and set up and voila everything is just super))) and most importantly connect this small remote control if you don’t do this the setup makes no sense!

Pros: As a non-melaman, I was a fan! It pumps normally, it’s enough =) after about 20 minutes my head starts to hurt =))))

Disadvantages: I didn’t find it, the only problem is when the sound is turned off the sub hisses =( and I didn’t find a high-quality performance. I was tormented for a long time by this question about hissing, this is a feature of the Sub, it doesn’t affect the sound! And the hiss from the volume control, if it’s turned off, then everything is fine, or do it at MAX” =_) generally invigorating!

Comment: For your money it's the best! 2108 downloads normally for me =) enough with a reserve =-) especially if you configure it correctly!, and I advise it.

Where are low frequencies used?

The transmission of low frequencies is especially important when watching modern films where scenes with special effects are used, when listening to electronic music. Low frequencies are also common in video games. Actually, this is one of the most important advantages of the Bandpass subwoofer: it can be used not only in a car’s speaker system, but also in the house. The Mystery subwoofer (active or passive) is becoming the choice of most consumers due to its environmental resistance and reliability. But to use the device in a car, you will need to purchase additional cables and adapters.
