1. RCA input Used to connect the amplifier to the line output of the head unit. The RCA output is used to connect a second amplifier. 2. Low frequency level control (BASS BOOST) This control is designed to smoothly adjust the gain boost at a frequency of 45 Hz within the range from 0 to +12 dB. 3. High-pass filter When connecting speaker systems smaller than 6x9 inches to the amplifier, it is recommended to set the crossover switch (6) to the H P position and set the HIGH PASS control to a frequency value of 65 Hz or higher to avoid damage to speaker systems by low-frequency signals. 4. Low Pass Filter When connecting a subwoofer to an amplifier, set the crossover switch (6) to L P. Set the crossover frequency to 100 Hz or lower, otherwise the speakers may be damaged. 5. Input signal adjustment (Level) This knob (5) is designed to adjust the amplifier input signal level. For correct settings, first move the control (5) to the MIN position, and the head unit volume control to the 3/4 position from the maximum (BASS and TREBLE controls in the zero position). Then slowly turn the Level knob (5) towards the MAX position. Note: If the sound becomes distorted, turn the control back a little. 6. Crossover switch The crossover switch allows you to select the speaker output mode: LP (low-pass filter), HP (high-pass filter) or OFF (filter off). 7-8. POWER and PROTECTION indicators These indicators show the operating modes of the amplifier: POWER - the amplifier is turned on and operating normally, PROTECTION - the amplifier has turned off due to overload or overheating. 9. Fuses Fuses are designed to protect the amplifier from overloads. Make sure you use the correct fuses. 10. +12V terminal The terminals are designed to supply (+) power to the amplifier. Connect to the (+) terminal of the car battery using a cable with a cross-section of up to 4 Ga. Install a fuse in this circuit near the battery. Note: This connection is made last when installing the amplifier (to prevent damage). 11. REMOTE INPUT (RMT) terminal The terminal is designed to turn on/off the amplifier by applying (+) 12V to this terminal. Typically, this signal appears at the output of a switched-on head unit designed to control an active antenna or other equipment. If there is no such signal, connect this terminal to the ACC circuit of the vehicle ignition switch. 12. GROUND (GND) terminal This terminal is designed to supply (-) power to the amplifier. Connect directly to the car body using a cable with a cross-section of up to 4 Ga. Note: This connection is made first when installing the amplifier. 13. Terminals for connecting speaker systems Terminals are designed for connecting one or more speaker systems. Follow the "2/1 channel (two or one channel)" connection diagram in the instruction manual.

Good nutrition is the key to success

The amplifier connection procedure begins with the power wires. Wiring is the most important element of a car audio system; the volume and sound quality depend on it. Amplifiers need a stable power supply, otherwise the power will not be enough and the sound will become distorted. To understand why you need to pay attention to the quality of wiring and how it affects the sound reproduced by a loudspeaker, you need to know what a music signal is.

Some suggest that it represents a sine wave, however, the musical sinhala is characterized by a large difference between the normal and peak value. If sharp signal bursts are not important for car speakers, then in the case of an amplifier the situation is completely different. If the signal exceeds the permissible power for even a second (or even a millisecond), then these “anomalies” will be audible even to those who cannot boast of a good ear for music.

If the car amplifier is connected properly, the signal will flow through the wires undistorted. Carelessly done work or incorrectly selected wire cross-section will result in the sound being more compressed, rough and sluggish. In some cases, wheezing may also be clearly audible.

How to choose a wire cross-section?

Wire is the most common metal with a certain level of resistance. The thicker the wire, the lower the resistance of the wire. To avoid sound distortion during large voltage fluctuations (for example, when playing powerful bass), you must install the correct gauge wire.

It is worth noting that the cross-section of the positive cable should not be larger than the negative one (the length does not matter).

An amplifier is considered to be a rather electrically intensive device. For its effective operation, high-quality grounding is necessary so that it is possible to receive the necessary energy from the battery. To choose the correct wire cross-section, you need to make some calculations. First, look at the instructions for the amplifier (or directly at the box from the manufacturer, if there is no documentation, use the Internet) and find the rated power value (RMS) there. Rated power is the signal power an amplifier can deliver over an extended period of time to one channel of 4 ohms.

If we consider four-channel amplifiers, they usually have a power of 40 to 150 watts per channel. Let's say that the amplifier you purchased produces 80 watts of power. As a result of simple mathematical operations, we find out that the total power of the amplifier is 320 W. Those. How did we calculate this? It’s very simple to multiply the rated power by the number of channels. If we have a two-channel amplifier with a rated power (RMS) of 60 W, then the total will be 120 W.

After you calculate the power, it is advisable to also determine the length of the wire from the battery to your amplifier and you can safely use the table to select the required wire cross-section. How to use the table? On the left side the power of your amplifier is indicated, on the right you select the length of the wire, go up and find out what cross-section you need.

The table shows the cross-sections of copper wires, remember that a large number of sold wires are made of aluminum coated with copper, these wires are not durable and have more resistance, we recommend using current copper wires.

Fuse selection

In order to secure the connection of the car amplifier, it is necessary to protect the power supply from the battery to the amplifier using a fuse. Fuses should be placed as close to the battery as possible. It is important to distinguish between a fuse that protects the device itself (whether it is an amplifier or a radio) and a fuse installed on the power wire.

Connection diagrams for a subwoofer in 1 ohm, as well as 1+1, 2+2, 4+4 ohm

In order to successfully connect a subwoofer in your car and not burn anything, you will need everything - nothing. The subwoofer itself, one or two, is a power amplifier with sufficient power reserve, and this is at least a quarter more than the total power of both connected subwoofers. You will also need wires of sufficient quality, possibly other components of the audio system - head unit, crossovers and other devices.

But having devices alone in the household is not enough; we also need knowledge. To get them, we will look at various diagrams for connecting a subwoofer in a car; these diagrams are suitable for the most popular subwoofers of such common brands as Pioneer, Mystery, Ural, Supra and subs from other manufacturers. A subwoofer, or even two, can be connected to a power amplifier in a variety of ways, most often this is one of the connection types: serial, parallel and independent. The circuits are also divided into connections in 1 ohm, 1+1 ohm, 2+2 ohm and 4+4 ohm. Any of these methods of connecting subwoofers to an amplifier contains some nuances and rules, which we learn about from connection diagrams and a video lesson from the YouTube channel of the famous car audio store Loudsound.

Connection options: independent, serial and parallel methods, 1+1 ohm.

Connecting one subwoofer in serial and parallel way. 1+1 and 2+2 ohms. Pay attention to the impedance of different connection methods.

Also one subwoofer with two coils of two ohms - connection in series and parallel, in 4 (2+2) ohms and 1 ohm.

The same method of connecting 2 coils is a little more detailed. Serial connection 2+2 Ohm.

Connecting two fairly powerful subwoofers with two 4 Ohm coils using a 4+4 connection diagram - working in 4 Ohms. Serial connection.

Various connection schemes. Serial and parallel connection. Works in 1 Ohm, 2 Ohm, 4 Ohm, 8 Ohm.

The same diagram as presented above, in this form you may come across in various instructions, textbooks and other technical literature. We present it to you so that you can read any diagrams. Works also in 1 Ohm, 2 Ohm, 4 Ohm, 8 Ohm.

Video training for connecting a subwoofer in a car

An excellent addition to the diagrams, or even the diagrams are an addition to it. Video lesson from Loudsound in which they talk in great detail, clearly and clearly about the correct connection of subwoofers in a serial and parallel way. From the video you will learn how to select an amplifier, navigate the power of subwoofers, how not to make mistakes, and not to plant or burn anything. The knowledge presented in the video will save you from many mistakes, help save you time and money, and protect your equipment. We strongly recommend viewing!

Stereo (2-channel) and bridged connection

Stereo is a standard two-channel connection used for high-quality sound reproduction.

We need a bridge connection to increase the power delivered by the sound amplifier by reducing the resistance. Its essence is approximately the same as that of parallel connection of subwoofers.

Options for a two-channel stereo connection to an audio amplifier, as well as a bridge connection “bridge mode” (single-channel connection) of a subwoofer, and connecting a radio to an amplifier + connecting the amplifier to a battery.

Detailed wiring diagram for the subwoofer and other audio system components, view from the amplifier. Here we see the connection of a subwoofer via a bridge connection. As well as a possible option for setting up an audio amplifier.

With a bridge connection we can connect not only a subwoofer, but also connect two power amplifiers. The meaning of this action is the same - an increase in the power output from the amplifiers. You can see how to do this from a video about a bridge connection of two amplifiers from the Loudsaind YouTube channel.

More about connecting a subwoofer to an amplifier and radio in a car

We looked at possible schemes for connecting subwoofers to a power amplifier. In addition, in the presented video, we were told in sufficient detail how to do this carefully and without harm to the equipment. And yet, in order to assimilate all this information, you will need elementary, so to speak, school knowledge of physics about the nature of electricity, the flow of currents, voltage and current strength, how they are measured (power - in Watts, voltage in Volts, current strength - in Amperes, resistance - in Ohms). Without this primitive knowledge, you will do everything “at random”, risking not only the equipment, but also your own health, which, you see, is the most important. When working with currents, including the power supply system in a car, you must follow safety precautions. The wiring must be well insulated; there should be no rings, bracelets or other metal jewelry on your hands, so as not to short-circuit the contacts with them. However, this is all a separate, extensive topic, or rather even a cycle of themes. We mentioned this only to once again remind you of the need to follow safety precautions. We will be very glad and grateful to you if you listen and don’t forget about it! Thank you also for reading our article, we wish you good luck in connecting subwoofers in your car! See you on the article pages of our website!

Connecting interconnect wires and control (REM)

To lay the cable, you need to find the linear output on the radio. The linear output can be recognized by the characteristic “bells” that are located on the rear panel of the radio. The number of linear outputs differs in different radio models. Usually there are from one to three pairs. Basically they are distributed as follows: 1 pair - you can connect a subwoofer or 2 speakers (labeled as SWF) If there are 2 pairs of them, you can connect 4 speakers or a subwoofer and 2 speakers (outputs are labeled F and SW), and when there are 3 pairs of linear wires on the radio, you can connect 4 speakers and a subwoofer (F, R, SW) F This is Front i.e. front speakers, R Read rear speakers, and SW Sabwoorer I think it’s clear to everyone what that is.

The connection will require an interconnect wire, which should never be skimped on. It is prohibited to lay the interconnect cable near the power wires, as various types of noise will be heard when the engine is running. You can run the wires both under the floor mats and under the ceiling. The latter option is especially relevant for modern cars, in the interior of which there are electronic accessories that create interference.

You also need to connect the control wire (REM). As a rule, it comes with interblock wires, but it happens that it is not there, purchase it separately; it does not need to be of a large cross-section - 1 mm2 is quite enough. This wire serves as a control for turning on the amplifier, i.e. when you turn off the radio, it automatically turns on your amplifier or subwoofer. As a rule, this wire on the radio is blue with a white stripe; if it is not there, use a blue wire. It is connected to the amplifier to a terminal called REM.

How to connect a subwoofer to an amplifier

Single channel connection

Connecting a subwoofer to an amplifier is not difficult; just connect the amplifier's audio output jack to the subwoofer coil or coils using speaker wires.

The wires should not be thin. In most cases, choose copper wiring with a cross-section of 4.2 square meters. mm and there will be no problems.

Connecting speaker wires

This subwoofer connection diagram is suitable for one channel of an amplifier or monoblock. If a 1-channel amplifier has two pluses and minuses, then don’t get lost, these pairs are simply paralleled for ease of switching. And it makes no difference which of the pluses and minuses the corresponding wire is connected to.

Monoblock is a single-channel amplifier designed specifically for subwoofers.

Connecting a subwoofer with a bridge

In the case of using a multi-channel amplifier, the sub can be connected to two channels simultaneously, using the minus of one and the plus of the other, this connection is called bridged, with this method the power output by the amplifier increases significantly (see the specifications for specific numbers).

So you can connect a subwoofer to a two or four channel amplifier, using 2 channels for acoustics, and the remaining 2 for the subwoofer.

To connect a subwoofer with a bridge, make sure that your amplifier supports this feature.

If you connect a low-frequency speaker to an amplifier by changing the polarity, that is, connect the plus of the subwoofer to the minus of the amplifier output and vice versa, then the speaker will work in antiphase, there is nothing wrong with that, sometimes such a connection is used intentionally if the amplifier does not have phase adjustment (more about adjustment phases).

Connecting the subwoofer coils

The technical documentation for the subwoofer states the resistance of its coils (1 Ohm, 2 Ohm, 4 Ohm, rarely 0.5 Ohm), and the technical documentation for the amplifier indicates what resistance it can work with, this information is needed so that you connect correctly and effectively subwoofer to amplifier. The lower the resistance of the sub, the more power the amplifier will produce, provided that it can operate at this resistance. A subwoofer speaker may have several coils (1 or 2, rarely 4).

Amplifier connection diagram

Connecting a two-channel and four-channel amplifier

We have combined this section because these amplifiers have a very similar connection diagram, one might even say more simply, a four-channel amplifier is two two-channel ones. We will not consider connecting a two-channel amplifier, but if you figure out how to connect a four-channel amplifier, then you will not have any problems connecting a two-channel amplifier. Most car enthusiasts choose this option for their installations, since this amplifier can connect 4 speakers, or 2 speakers and a subwoofer. Let's look at connecting a four-channel amplifier using the first and second options.

Connecting a 4-channel amplifier to a battery is recommended using a thick cable. How to choose the right power wires and connect the interconnects, we discussed all this above. Amplifier connections are usually indicated in the manufacturer's instructions. When an amplifier is connected to an acoustic system, it operates in stereo mode; in this mode, this type of amplifier can operate under a load of 4 to 2 ohms. Below is a diagram of connecting a four-channel amplifier to speakers.

Now let's look at the second option, when speakers and a subwoofer are connected to a four-channel amplifier. In this case, the amplifier operates in mono mode, it takes voltage from two channels at once, so try to select a subwoofer with a resistance of 4 ohms, this will save the amplifier from overheating and going into protection. Connecting a subwoofer will not be a problem; as a rule, the manufacturer indicates on the amplifier where to get the plus to connect the subwoofer, and where to get the minus. Take a look at the diagram of how to bridge a 4-channel amplifier.

Connecting a monoblock (Single channel amplifier)

Single-channel amplifiers are used for only one purpose - connecting to a subwoofer. A notable characteristic of amplifiers of this type is increased power. Monoblocks are also capable of operating with resistances below 4 ohms, which is called a low-impedance load. Monoblocks are classified as class D amplifiers, and they have a special filter for cutting frequencies.

Connection diagram of the amplifier to the 4-channel radio, to the Pioneer subwoofer: video

Many car owners are not satisfied with the power and sound quality of their radio. In order to solve these problems, an external amplifier is installed. The external audio amplifier operates on a voltage of 12 V; thanks to the built-in voltage converter, it increases it from 12 to 100 V.

How to connect?

After installing an external amplifier, the radio's power, maximum volume and sound quality increase.

How to choose an amplifier

When choosing an amplifier, you need to pay attention to the following details:

• The amount of power for each channel. This is one of the main characteristics of an external amplifier. It must match the power of the radio and other equipment.

Scheme

• The power of each channel in the amplifier should be less than the power of the subwoofer speaker and rear speakers. If this condition is not met, you may get unpleasant wheezing in the speakers.
• The amplifier and speakers must have equal load impedance. It is acceptable if the speakers have this figure slightly higher.
• The frequency range of the external amplifier should not be less than 20 Hz - 20 KHz.
• If a subwoofer is installed in the car, then a two-channel amplifier is needed.

Installation and connection steps

Most often, the amplifier is connected using wires directly to the battery. The external amplifier will be located in the trunk or interior of the car, and the wiring runs through the holes in the engine compartment. The wires must be well insulated with electrical tape.

The positive wire, almost always red, is connected to the positive terminal of the battery and plugged into the corresponding connector in the amplifier. And the negative wire, black, is connected to the body and inserted into the connector designated GND (GROUND). The remaining two sockets are used to connect the radio and signal cable. Almost all radios have outputs for connecting an amplifier and supplying sound to it.

For a four-channel amplifier, you need to use special adapters, and if the receiver does not have linear outputs, then the wire is laid directly to the speakers, where special inputs must be provided.

The wiring from the radio to the amplifier is laid inside the car, most often under the door trim. Under no circumstances should the signal cable be laid on the same side as the power cable. This will cause interference and loss of sound quality.

When choosing a place for the amplifier, you need to take into account that it gets very hot during operation, so it is best to install it in an open place, for example, a trunk shelf. If the amplifier is installed in a narrow space, it will require additional cooling. To do this, you can use a couple of computer coolers.

Another important factor when choosing the location of the amplifier is the distance from it to the acoustics. It is advisable to reduce it to a minimum so that the wires are as short as possible. In this case, the likelihood of interference during music playback will be minimal.

With the correct selection and installation of an external amplifier, you can significantly improve the quality of the sound reproduced by the radio, eliminate interference and increase the power of the radio.

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.

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.

Mystery active subwoofer connection diagram

You can also connect a subwoofer yourself. The step-by-step instructions, which are sold in the kit, offer many photos with the help of which even an ignorant person can complete this process. In addition, you can familiarize yourself with a variety of videos on this topic, of which there are a lot on the Internet. The price of home installation will be much lower than that offered in car services.

I want to say right away that I didn’t count on the sound quality, so there isn’t much of it) But the desired effect of the sub is present) I bought the sub for 3,500 rubles)

I was looking for a pinout manual for a long time, since I didn’t get any information from the old owner. As a result, I found it on the drive - www.drive2.ru/l/388601/. I post it here: “1. Attach the silver (black) hose to the car body near the subwoofer location (preferably under a good bolt).2. Blue (red) with a fuse - route to the battery and connect to its positive terminal. (By the way, remove the fuse in advance and insert it back into the holder only after all connections have been completed).3. Purple wire – route to the radio and connect to the active antenna (additional amplifier) ​​control wire coming out of the REMOTE CONTROL radio (usually blue).4. Determine whether there are linear outputs on the radio. 4.1. If there is, then using a double shielded cable with RCA connectors (tulips) connect the linear output of the radio with the linear input of Saba.4.2. If there are no line outputs, then connect in parallel to any pair of speakers (front or rear) using the “high level” input. The gray and gray/white wires are parallel to the right speaker, and the green and green-white wires are parallel to the left. The main thing is not to confuse: “single-color” wires to the minus of the speakers, and “two-color” wires to the “+” of the speakers. Install the bass control WHERE YOU WANT)) and use a black cable with “telephone connectors to connect to the Sub.”

Well, now closer to the point. To begin with, I bought a set of speaker wires for about 1,500 rubles and a “high-level” input for about 300 rubles, as well as a bunch of attachments and tips and wires for 200 rubles.

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”).

Daisy chain connection of two subwoofers

What could be easier than connecting a single-coil subwoofer to a monoblock or multi-channel amplifier. It's a completely different matter if the subwoofer has two voice coils or two or more of them. A two-coil subwoofer, as well as two, three or more subwoofers, can be connected in four ways: each coil separately, parallel connection of coils, serial and combined. What each of these subwoofer switching options gives is, first of all, versatility, different capabilities. Let's consider each option separately. But first of all, you need to understand what happens when the coils are connected in parallel or in series. When the coils are connected in parallel, the total resistance, roughly speaking, becomes half as much. For example: if we connect two 4 Ohm coils in parallel, we get a total resistance of 2 Ohms, if we connect two 2 Ohm coils, we get a total resistance of 1 Ohm.

The opposite effect occurs with a series connection. When connecting two 4 Ohm coils in series, we get a resistance of 8 Ohms, when connecting two 2 Ohm coils, we get 4 Ohms. etc.

-Connect each coil separately. This option allows you to connect a powerful two-coil subwoofer to a less powerful four-channel amplifier if it is not possible or not possible to purchase a powerful monoblock. Naturally, the resistance of the coils must correspond to the operating load of the amplifier in a bridge connection and the GAIN controls must be at the same level.

-Parallel connection of coils - subwoofers. As described above, when connected in parallel, the resistance is halved, allowing the amplifier, operating at a lower load, to deliver more power. But as they say, “if it leaves somewhere, it will definitely arrive somewhere.” In this case, this is true, only on the contrary, the power has increased, and the amplifier’s control over the subwoofer has decreased, as a result of which the bass becomes smeared.

-Serial connection of coils. If the amplifier is powerful, why not, increase the impedance (resistance) and get a more developed bass. I would also like to add that if the resistance of the connected coils exceeds the permissible load of the amplifier, this is not at all scary, it’s just that the output power of the amplifier will be less. Let's say an amplifier with a declared operation for a load of 4 ohms produces 500 watts, and with a load of 8 ohms, for example, it will produce 350 watts.

-Combination connection. Subwoofers are coils that are simultaneously connected in serial and parallel connections for switching to a specific load. There are a great many connection options, it all depends on the number of subwoofer speakers, the resistance of the subwoofer voice coils and the capabilities of the amplifier.

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.

The Mystery subwoofer is easy to connect, so you can do the job yourself. Properly installed equipment will function smoothly and delight the car owner with high sound quality.

How to connect Mystery?

You have taken the right step towards improving your audio system by purchasing an amplifier. For lovers of high-quality sound, we have prepared instructions on how to connect a mystery amplifier and make the sound of your audio system louder and more pleasant.

Step-by-step connection Mystery

1. Negative wire: it is connected to the GND terminal on the amplifier with one end, and the other on the body. The area should be thoroughly cleaned first, which will ensure better contact. Please note that the negative wire should not be thinner than the positive one;
2. Positive wire. It is connected to the +12V terminal on the amplifier. The flask with the fuse is mounted in the gap of the positive cable, closer to the battery. This will protect the cable from short circuits and fire. Where the wire passes through the metal, use protection - a corrugation or sleeve, so as not to damage the insulation. Connect to the battery last.
3. Remote terminal. Almost every radio currently produced is equipped with a blue and white wire with stripes. When you turn on the audio system, 12V is supplied to this wire, which is responsible for directly turning on the amplifier. If you turn off the radio, the amplifier will also turn off. If this cable is not available, the Remote terminal should be connected to the ACC circuit.
4. RCA cables.
