Connecting the automorelifier to the linear input of the radio. How to connect a car amplifier if there are no linear outputs at the car radio. Making AUX on Auto Magnittol

Some car owners are not satisfied with the sound of a regular radio. The situation can be corrected by installing an active or passive subwoofer. Installation of the device in the machine is possible on its own, for which the necessary materials and tools should be selected, familiarize yourself with the connection scheme and the step-by-step process algorithm. Then install the technique and connect its work will not be.

The main differences between passive and active subwoofers

To answer the question about the distinctive moments of active and passive subwoofers, it is necessary to figure it first, which represents each of the designs separately.

What is a passive subwoofer

Passive SAB is a design from one or several dynamic low-frequency dynamic heads (LC) enclosed in a single case, the material of which can be both plywood and wood. Such a device reproduces audio vibrations, you need to connect to an external amplifier. sound Frequency Through the LF filter that skips only a low frequency band.

Passive subwoofer is separate dynamics, filters and amplifier devices. Each of these blocks is made individually and when installing is connected to each other.

What is an active

Active SAB is a single ready-made acoustic block, consisting not only from the speaker and filter, but also a reinforcing device. Such equipment in the connection is somewhat simpler, also there is an opinion that sound quality exceeds sound from a passive subwoofer. But if you figure it out more, then the sound quality directly depends on how the setting is made.

Active subwoofer has a built-in amplifier, which saves a place in cars with a small free space. To connect to the radio, it is enough to serve meals and audio

The difference between them

To determine which design to give preference, it is worth considering the main points to which car owners pay attention when choosing:

  1. The price indicator is the cost of the active SABA above, due to the presence of an amplifier in the device and other expensive elements.
  2. Advantages of mounting - passive structures are more difficult in the installation due to the need to additionally install the filter and amplifier. The presence of an amplifier in the active system allows to save space, which is especially relevant for small cars.
  3. The sound quality - many may argue that the sound of the active system should be better. However, the sound directly depends on the correctness of the system setting. If you proceed from practice, then with high-quality adjustment of passive saba, the sound exceeds the operation of the active system.
  4. Easy settings - active acoustic system More advanced setup features, but if a good external amplifier is used, then this feature is reduced to no.

Pros and cons of systems

The positive parties of the passive subwoofer refers to relatively low cost due to the lack of a built-in amplifier. In addition, the use of passive systems allows you to collect an acoustic device with those requests that will correspond to high quality sound In your understanding. In order to get a subwoofer with optimal sound quality, you will need to choose the amplifier, frequency filters, as well as a set of dynamic heads in boxes. Compared to active, various types of enclosures are used for passive structures: Bandpass, phase inverters, and standard boxes. As for active devices, the use of buildings is difficult different types Due to the need to accommodate additional electronics.

The main advantage of active is the presence of a built-in amplifier and filter, which allows you to connect the system with a car without additional devices. This positive feature is simultaneously a disadvantage. Due to the fact that in one case there is a speaker and electronics, and you have to sacrifice something. The main nuance is the insufficient power of the amplifier.

How to install a subwoofer in the car and connect it to the radio

To mount a subwoofer, in addition to the device itself, you will need such tools and materials:

  • wiring (nutrition, "tulips" and a plus wire to the amplifier and car radio);
  • fuse;
  • capacitor;
  • pliers and nippers;
  • insulating tape;
  • screed;
  • set of wrench and adjustable key.

Where to install

Sabe installation may present a real problem, which depends on the car model. And it's not just a device for connecting the device, but also in choosing a place to install it. As the owner of a minivan or hatchback, the question is not raised by the place, as the trunk has large sizes. With sedans, the situation is somewhat different and, as a rule, the SAB is mounted in armrests either on the rear shelf. A cabriolet is considered the most inconvenient body type, since such machines have a small trunk volume. However, with a great desire and in such cars, you can install the device under consideration.

Passive connection

Consider a consistent device installation algorithm. The installation will have to spend about 1-3 hours, which depends on the experience and model of the machine. One of the complex stages is to lay the power cable to the amplifier. Since the subwoofer is mounted in the trunk, then all the wires need to be laid through the salon to the power supply. Before starting work with the battery, the terminals are removed, which will eliminate the possibility of short circuit.

  1. The first thing you need is to find a technological hole that is closed by a special plug. On domestic car, it may be absent, as well as the hole itself. Therefore, it will have to drill it and after pulling the cable to make a seal seal. Best of all, to exclude wire overs, insert a piece of hose into the hole.
  2. Wiring in the subcontrol space can be located in a regular harness and displayed in the cabin. Previously need to decide where and how the feed cable will be laid. For wires in some places it will be necessary to remove the trim, also lining thresholds. Flames and pinching of wiring should be avoided. After installation, all facing elements are installed in its place.
  3. The luggage compartment of the wire to the amplifier is also paved through the hole in the body. Power to the device is connected to the observance of polarity.
  4. After taking power to the amplifier, it must be connected to the radio. In this case, the Wires are needed according to the type "Tulips", as well as a wire that allows power to control the power of the amplifier. For dismantling, the radio will use special keys, but you can take advantage of a knife or a suitable score.
  5. "Tulips" connect according to the details of the connector. If it is necessary that the simultaneous inclusion of saba and radio tape recorder occurred, then the corresponding positive wire.
  6. Then we skip the wires together with the power cable through the salon. We produce the connection of "tulips" to the amplifier.
  7. If the feed wire was connected to the radio, then it should be applied to the amplifier so that the devices are turned on simultaneously. We are looking for a terminal and connect it with a radio tape recorder.
  8. It remains to connect the subwoofer with the amplifier. When installing a two-channel amplifier, for power distribution, both channels are connected to the device under consideration.

Adapter high level Used for radio without linear output connectors. The device converts a signal from the output of the radio in the linear signal.

Connecting the subwoofer from the computer to the radio

Sometimes quality regular music In the car does not suit and different thoughts arise to improved sound. One of the questions is to connect a computer subwoofer to the radio. In fact, the device can be connected, and in two ways: feeding power through the inverter 12 / 220V or finding the necessary contacts (+ 12V) on the booster for the subwoofer. To do this, we need to arm a tester and have little experience in electronics. Having understood with nutrition, apply the audio signal to the subwoofer input by taking it from the linear output of the radio, by means of the shielded cable of the desired length.

Connecting through a crossover

Before you consider the connection of the subwoofer through the crossover, it is necessary to figure out what is the device. The crossover allows you to divide frequencies in ranges, i.e. Plays the role of the filter. For example, there are such speakers called "sakers". If you do not use the frequency filter, then the signal of the entire frequency range would be fed to the dynamic heads - from LF to HF. Without splitting the signal, the detail of music will be worse. Crossovers are active and passive type, as well as single and two-band.

Pros, Cons and Connection of the Passive Crossover

There are no active elements in the passive filter, i.e. it consists of inductors, resistance and containers. This flows out a significant minus - the loss of signal power. Also, the disadvantages should be selected on peak load, which leads to a rapid output of the device. To connect a passive crossover, it is placed immediately before loading, i.e. before dynamic heads. In this case, you can use only one amplifier, which is an advantage. Such filters can be mounted in acoustics or represent a separate unit.

Pros, Cons and Connect Active Crossover

The active filter is installed in front of the amplifier, so it is impossible to use one device to enhance the signal. In this case, the speaker is connected to a separate amplifier channel regardless of the type of frequency. Of the advantages of the active filter, you can select the ability to accurately adjust the frequency sections. This is this factor and is determining in more high cost Such a design compared to passive.

Security measures

  1. Any work in the car related to electrical equipment must begin with de-energization, i.e., turn off the terminals from the battery.
  2. All connections must be reliable and safe, for which seals, tape, clamp, special corrugations are used.
  3. For mounting, only high-quality wires are used.
  4. The selection of the fuse should be carried out in accordance with the passport data of the connected devices.
  5. Acoustic equipment in the car should be fixed comfortably and reliably.

Video: Passive subwoofer connection

Installation of the subwoofer in the car allows you to get a decent sound quality. If a passive design is used, you can select each of the system devices by specified characteristics. To independently install, it will be enough to purchase the necessary components and familiarize yourself with possible connection schemes, while you can save on a visit to the car service.

Good and loud music in the cabin of the car - this wanted many motorists, especially young people. But there is some problem, not every machine is already equipped with a high-quality audio system. Therefore, in this article we will fully fully and intelligibly tell you how you can independently connect the subwoofer to the standard magnetol, to the one you already have, installed by the manufacturer's plant.

True, I want to immediately make a reservation. What if you decide to fulfill all the work and connect an active subwoofer, then the responsibility will be personally at you. But you do not need to experience unnecessary fears if your hands can keep a screwdriver and passatati, then connecting the amplifier to the standard magnetol, it will be forces.

How to connect a subwoofer to a regular radio, without linear outputs

There is a desire to listen to your favorite performers while driving, there is a car, but it, unfortunately, does not give the desired effect, the music plays, but I would like something more powerful. For this, you need a subwoofer, but the connection of Saba is still accompanied by some difficulties. On it, like any other amplifier, you need to use meals, as well as connect the cable to which the audio signal will be transmitted.

And here, if you, not an advanced amateur, you can go to a dead end, because in the car car you do not find a single hole where it would be possible to connect the desired amplifier. It is possible to constitute a lawsuit whether it is possible at all, and if possible, how to connect Amplifier for regular magnetol?

1) Acquisition of a new magnetic

The first way is good for those who are poorly understood in radio mode, but does not have special restrictions in cash. It is necessary to simply go to the car and purchase a new radio tape recorder, more modern, and it is possible that all questions will be solved by themselves. This method is really not bad, but requires compliance with some formalities. For example, your car must support the purchased regular head unit. Also in the radio should be support function, so that the connected subwoofer worked, and gave a wonderful sound. Well, the last important point is the cost of headquarters, with the modern crisis, their price jumped to the price spacecraft. But, as already written above, if the money is not a problem, then everything is immediately solved, otherwise we read further.

2) contact radio amateurs

So, if you are not a millionaire, and they are not very well versed in the wires, then for you the best way out will appeal to experienced radio amateurs.

You can find them in small workshops. Some experts are literally for counting minutes, in your eyes, will figure out your magnetol, additional wires solder and bring them out the RCA connectors. The scheme is simple, but 100% working. You already need to connect an amplifier or subwoofer to the dismanded contacts. If the master is good, then it will provide you not only a wonderful sound, but also full safety in the car.

3) Install a linear converter


The following option is suitable for those people who themselves are poorly understood in the subtleties of radio wave, but do not want to contact others. In this situation best exit Buying a level converter. It is through it that can be connected between any two instruments, a head unit without the outputs and subwoofer, or an amplifier. You can buy this converter at any autoswool store. This device itself is simple, and therefore will not delve into its inner world, but it has two tulips from the outside on one side (so called audio connections - RCA), and on the other - four wires.

Even a schoolboy can cope with the conversion of the converter, the main thing is not to confuse the contacts, plus and minus join the right dynamics, the remaining two wiring are connected to the left speaker. That's all, your high-level frequencies turn into low-level, and you fully, as far as possible, enjoy music. And one more important moment, which is due to such a connection, all your electronics will be complete.

4) choose an amplifier or a subwoofer with low-level entrance

The last option is perhaps the easiest, but again everything rests on money. That is, having a certain amount in the hands, you again goes to the electronics store, and buy the so-called active subwoofer or an amplifier with a low-level entrance. Also, not discovered in the principle of his work, we note that in this device the linear converter is already built into. You connect it according to the instructions for the speakers and enjoy the music.

Often, during the design of the speaker system, not all technical characteristics of the car radio are taken to attention. After all, users simply do not imagine whether the installation will be carried out additional components. And at a certain stage it turns out that the car radio is simply not equipped with linear outputs. How to do?

In order to obtain the desired linear signal, you can use such methods:

· Directly on the radio to fall linear output.

· Take advantage of the appropriate consoles in order to achieve the desired signal.

· Supply using an additional preamp. So, it will be possible to significantly increase the level of the signal.

· The use of the amcuscant, which has a high-level entrance.

Based on the optional option, it can be divided into groups. In the first case, no additional actions for the radio are not performed, in the second - direct intervention is required. But do not forget that as soon as the integrity of the headquarters is broken, you will not be able to use the guarantee. Therefore, we choose exactly the first option.

Failure from Linear Release Magnet

In order to succeed in this case, you need to have certain attentiveness, as well as hands. Be sure to pick a microcircuit. About what kind of kind, you can understand from the image. By the way, it is connected directly to a large radiator.

As soon as the scheme is found, you need to set the label. After that, you need to find a datasheet, in order to determine the acceptable decay of the conclusions available on the scheme. It is from this input that the incoming signal is removed.

Undoubtedly, a prefix can be applied, with which the signal level will be reduced. Now, such equipment is actively focused on sale. And they have no special design features. And in the event that there is a need, it is possible to carry it out of its preparation, using schemes.

If you are not encountered every day with radio tape recorders, amplifiers and other sound reproducing technique, then you may well have a question - and what is this most "linear output" on the radio, why is it necessary and what is their number.

Linear layer output is designed to connect external sound amplifiers. It can be acoustics amplifiers, or an active subwoofer - in order to transmit sound from the source (car) to the amplifier, a linear output is used.

Under the concept of "linear output" implies non-balanced audio transmission type in which one signal conductor and earth is used, RCA connectors are used in automotive electronics (so-called "bells"). Also implies the signal level corresponding to the standard. IN car radio tape recorders This level is usually up to 2V, some devices (high-class) have a signal level up to 4.5-5V. The signal level at a linear output in the automotive electronics is of a serious value, because the car is a source of a huge amount of interference and the higher the level of the useful signal transmitted through interconnect cables, the less interference will be heard from electronic systems car.

The higher the signal level at a linear output - the better, no wonder all high-class car machines have a linear output with a high level and it is particularly emphasized in specifications.

How many linear outputs should have a car radio?

Indeed, if you choose an automagnetol, then in specifications you can read about the number of linear outputs that can be different, for example, one pair, two pairs, three pairs. The more expensive the magnetol, the greater the linear outputs, it usually has "on board". How much should they be?

  1. One pair. Usually there are in all the most inexpensive radio tape recorders. Most often used to connect a subwoofer. Well, when a radio output radio tape recorder can control the level of this output (to adjust the subwoofer), if there is a built-in filter for a subwoofer (LPF), then it is generally excellent.
  2. Two pairs. Usually these are frontal and rear outputs for the construction of the system with the amplification of the "front + sub-sab" or "front + rear". This is usually the Magnitoles of the Middle Price Range, there are already necessary settings For subwoofer (see above), in general, excellent when the filter can be turned on on the front outputs low frequencies (HPF).
  3. Three pairs are optimal option To create a full-fledged system with an amplifier on all channels (front + rear + sub) or even complex embodiments, if the magnetic has a built-in crossover or even a processor.

The larger the pairs of linear outputs at the car radio, the more sophisticated audio system can be created. When buying, decide how much you need.

So buying a car radio. Decide which amplifiers you will connect to it later. If the amplifiers are not planned, then in reserve at least one linear output to connect the subwoofer is still not bad. And suddenly still wants to deliver?

What if the radio does not have a linear output?

If your car radio does not have a linear output, then it is most likely it is either very cheap or this is a factory radio. If there is no way out, but it is very necessary, then there are two options here - one is right and another simple.

The correct option is "dropping" linear outputs, i.e. Disassemble a radio tape recorder and display a signal from it after pre-amplifier and to the power amplifier chip. It is not for everyone to everyone, it is necessary to have an understanding of the circuitry of radio tape recorders and at least be able to keep a soldering iron in their hands. You can also contact a specialist.

A simple option is to use a high signal converter to linear. Such a solution is quite suitable if you need to connect, for example, an active subwoofer to a regular radio tape recorder, without any complaints about quality, because it is not an uncompromising solution in terms of sound quality.

What to do if the radio lack of linear outputs?

It happens that your car radio only has one pair of linear outputs and you need more. For example, you have already connected an amplifier to the front speakers, but I want to install a subwoofer with an amplifier, but there is no desire to change the radio. There are two options here:

  1. Remove the additional pair of linear outputs from the radio (see above), requires an understanding of what you do or better contact the master.
  2. Take the so-called y-splitter. This is a simple wire-splitter, there are two of their kind and they look like something like this:

Y-splitter (1 "Mom" - 2 "Pope")

Y-splitter (1 "dad" - 2 "Moms")

The first option (1 mum and two dads) is more often used when you install a four-channel amplifier. You take one intercomponent wire ("linear wire", "inter-block wire", "line", "bells") and connect to the radio tape recorder and stretch into the trunk. In the trunk you take this Y-splitter and you thus appear two pairs of linear outputs instead of one.

The second option (1 dad and two mothers) is used more often when you need to connect two separate components, such as an amplifier and an active subwoofer. Then you connect the Y-splitter to the radio and you already take two intercomponent wires, stretch where you need. The fact that you will have two wires will allow you to place the components in the trunk as you are comfortable - one in one corner and the other in the opposite example. IN this variant Minus the one that will have to buy two RCA cables instead of one.

You must not forget that when using the Y-splitters, you will receive a signal from one output, so the tape recorder will not configure the front-rear or front subwoofer!

The presence of a radio tape recorder depends on its assembly. But, as practice shows, many drivers when purchasing transport are preferred by options with an already built-in audio system. She is good quality And provides clean sound of music.

Progress does not stand still, and new models of devices regularly appear. They are equipped additional featuresallow you to raise acoustics. Such a system allows you to listen to music without distortion with huge dynamic range. As a result, the musical compositions sound bright, naturally and reliably.

Linear output on the standard radio: features

In practice, it is proved that an external power amplifier is the main additional device To the radio tape recorder, which helps to reveal and improve the quality of the diversity of sound. This procedure Can be carried out in several ways. The simplest and inexpensive referring to the installation of the subwoofer. It improves the quality of the sound of low-frequency musical compositions.

Another way is to replace acoustics and installing the amplifier. You can also carry out more radical manipulations. They imply the installation of a new crossover, surround sound processor and other things. But this is not the whole list. There are quite a lot of ways to help improve musical painting in the car.

Combines all these methods what is used external devices. But you can apply for this purpose and a linear output, which has many radio tape recorders. In this case, the signal quality will be much higher and will be reproduced through the entire audio system.

How to make a linear output on a regular radio?

If the radio is not equipped with linear outputs, it is not worth upset. After all, the situation can be easily corrected. To do this, you can use different ways. For example, on the device itself, falling a linear output or use special consoles that will help achieve the required signals. If in the first case, apply an additional preamp, then the sound will significantly improve.

Speaking about these methods, they are divided into two main groups. The first includes those devices that do not perform additional actions. But the second provides them. But do not forget that any interventions in the integrity of the headquarters lead to loss of the ability to use warranties that are provided for the radio. Therefore, it is better to give preference to the first method.

Linear way outline Toyota

Failure of linear outputs from a regular radio tape recorder is not a complex process, but requires care and responsible approach. Especially if it is done with your own hands. The first thing to start is the selection of microcircuits. Its species is provided in the photo. Moreover, it joins the radiator.

After the scheme is defined, you need to set the label. Next, you can proceed to the search for a datashet. This will determine which slacking already exists in the scheme, and which one can apply in our case. This information It is extremely important because the signal is received from the input.

IN lately The prefixes that reduce the signal level become particularly popular. This design is quite simple and does not have features. Therefore, each will cope with its preparation and setting. It suffices to use the corresponding scheme.

Supplement from the linear output radio with the use of the preamp is very similar to the previous one. The course of action is no different. Therefore, it is also performed.

Spacking linear outputs on a regular radio

The splitting of linear outputs is to carry out several events. First you need to remove the frame that is around the device. It must be done carefully, as it is easy to damage. Next are unwind and removed all the vents that are visible. This will make it possible to remove the Magnitol's face and disassemble it into two parts.

After breaking the device, inside you can see the processor and amplifier. Next, everything becomes easier. So, near the amplifier is a sawing. She is responsible for the connection. Then you need to find four legs that are at the inlet of the amplifier. It takes a solder, and the rules are displayed.

You can use another method. It consists in using tracks on the board, which go from the entrance to the amplifier. One is aimed at first to the resistor, then into the condenser and amplifier. This configuration does not allow to transfer all acoustics. But you can correct the situation. To do this, you will need to solder a capacitor and a resistor. This will get the sound much cleaner and natural.

Spacking output on Chevrolet: instruction

Another method of obtaining linear outputs requires such actions:

  • Removing the Magnitole Frame;
  • Unscrewing screws;
  • Removing the device. To do this, you need to disconnect the connectors and antenna;
  • Disassembly of the radio. To perform this stage, you need to promote the screws, remove the cover, which is located on top, unscrew the screws that are responsible for fastening the CD drive. At the same time, the device is lifted and the train loop is disconnected;
  • Preparation of RCA connectors;
  • Shipping connectors and contacts. These elements are very small. To perform work, you need to use a soldering iron that is equipped with a thin stale;
  • Mounting drive to the board.

The linear outputs thus obtained allow you to get left and right channels that are located ahead. In this case, the served signals are adjusted to the volume and equalizer of the device. To get the rear channels, you need to use other resistor points.

Such simple actions - the supply of linear outputs from the standard magnetic - can be made time in the car is much more comfortable and more pleasant. In addition, the wonderful sound of the radio is able to improve the mood and charge positive. After all modern man It holds a lot of time in his car, and it is extremely important to make it comfortable.
