How to connect car receiver at home using a power supply

This article will consider how to connect the car stereo at home, and not in the car. In fact, there is nothing complicated in the procedure. But you will need some devices, which will be discussed below. Car radio receivers are able to provide high quality sound, which does not go in comparison with most of the amplifiers produced directly for use at home.

In addition, in any car radio, it is possible to connect an external source of a signal (TV, computer, telephone). And also a device for playing low frequencies (subwoofer). But not all receivers, unfortunately, allow you to connect subwoofers. This question will be considered below.

What do I need to make the connection?

The first thing you need is a power supply for the car stereo. It must meet all the requirements that will be considered in this article. Also, it is desirable to have a high-quality acoustic system. Do not forget that the radio tape recorder has a four-channel output. Consequently, you can easily make the system 5.1 - two columns from the front, two behind and a subwoofer. Of course, you need to have wires to connect a specific radio.

For normal operation it is necessary that the radio tape recorder be mounted neatly, preferably in the same housing as the power supply. It can be made from any material, but it will be easier to work with wood. After making the case, you can do it in order to achieve maximum harmony. Ideally, if all the acoustics, the case with the power supply and the radio tape recorder will have the same design.

Power Requirements

It is worth noting that before you connect the car stereo at home, you need to decide on food. An important parameter is the output current of the source. At high volume, the recorder's consumption increases, therefore, a powerful power supply is required . A good option is the one that is installed in computer power supplies. In addition, it has forced cooling, no additional filtration of the output current is required.

If you are going to make a power supply yourself, then it is necessary that it produce a current of up to 6 Amperes. This value will be enough for the car radio to work stably. However, if you need to connect a subwoofer amplifier , then you need to act proceeding from the situation, namely - from the current consumed by the device. The power supply for the car radio must have a high-quality cooling both natural and forced. Otherwise, semiconductor elements will fail.

Acoustics requirements

Now a little bit about the speakers, since the car stereo can not be connected at home without it. Pay attention to what kind of resistance of the speakers can be connected to the output of the radio. As a rule, it is 4 ohms, this standard has long been used. Consequently, the inclusion of an 8-Ohm load will not give the expected results. The sound will be completely different, the volume will be small.

Each speaker must be placed in a separate box. And it is desirable that in one case there were three playback devices - for medium, low, high frequencies. Of course, low frequencies will be, but not as effective as when using a subwoofer. And do not forget about the resonators, the quality of the sound depends on them.

Connecting the subwoofer

Now consider how to connect the subwoofer to the car radio. There is nothing easier if there is a special exit. It connects to the amplifier, and the last one - to the subwoofer. But what if there is no way out? Then you need to go along the path of least resistance and take the signal from one of the channels. But not from the output of the radio, but from the entrance. A weak signal is needed to feed the subwoofer. It is converted several times in the amplifier. The first thing he does is to filter the low frequencies.

With its help, everything that does not enter the interval of 20-60 Hz is cut off from the sound, for example (the adjustment is made on the amplifier itself). Then the signal goes to the amplifier stages. Depending on the manufacturer, there may be several. But often only one chip is put. Since it's easy to connect the Pioneer car receiver, let's see what happens when the signal is amplified further. There is no need to split it into channels (the amplifier works in the "mono" mode), then the chip is switched on by the bridge circuit. This allows you to increase the output power by half. Therefore, you can connect a subwoofer and not only if you have a connector for it. The main thing is to know the essence of the processes taking place in the system of these devices.

conclusions

Now you know how to connect the car radio at home, what accessories are needed for this, as well as the basic requirements for all nodes. To improve the sound of acoustics, you need to select the volume of the subwoofer based on the size of the room in which it will be installed. And, of course, observe the electrical safety technique.
