Long gone are the days when, sitting in the saloncar, you have to prepare for hours to listen to the mournful noise of the motor or the crackle of a radio jammer. Modern cars are equipped with stereo systems that can compete with concert halls for their rich acoustic effects. "Usilki" are connected to them so powerful that you can find out about the approach of the machine long before it appears in sight.
Let's talk about amplifiers
About which sound amplifier is better and which onethe model will suit his audio system, any driver thinks seriously, deciding to equip his salon with high-quality stereo equipment. What should I look for in addressing the issue?
- Dimensions.The driver must understand exactly where he will place his sound amplifier, and should choose the technique based on the parameters. Otherwise, an unpleasant situation may arise when the device is purchased, and there is simply nowhere to fit it. Those. The first rule is the harmony between the dimensions of free space in the cabin and the dimensions of the amplifier.
- Device class. The classification begins, as usual, with letter A:
- Class A.The sound amplifier related to it has little relevance to its functional role. Devices of this type are characterized by low-frequency distortion, a weak sound, as a result, in order to hear music when the engine is running at full speed, the volume has to be set to almost the maximum. In addition, this sound amplifier heats up quickly due to the high energy consumption. This does not add to the viability of either the device itself or the engine battery.
- Class B devices. They are much better than the previous ones in terms of technical parameters, quality of sound transmission and thermal stability.
- AB class.The sound power amplifier related to it is the average between classes A and B in terms of the parameters of the device. Most often they are found in cars and their wide choice is presented on the market of electrical engineering.
- Class D, in a different way - digital signal amplification.Previously, devices with low frequencies were characterized in this way. At the present time, the so-called broadband car audio amplifier. True, the quality of his work is somewhat inferior to the previous one. Therefore, today it is the AB class that is distributed more than others.
Modern car audio systemsquite complicated. If a couple of decades ago, the driver installed only two speakers in the cabin, then the current "stereo centers" may well be tricked with home theaters. To date, manufacturers produce amplifiers with channels from one to six. The traditional two-channel device is considered - according to the number of CDs recorded on standard CDs. What are the most common wiring diagrams?

- "Amp" with the scheme "front and subwoofer."Such are widespread among motorists. Easy to operate, standard on issued quality parameters. The sound reproduced quite nicely. Channels from 3 to 4 or “bridge” connecting two to one channel.
- Multimedia scheme for the cinema in the car.
The most suitable option is considered to be such an amplifier, which has two channels, if installation permits. More economical in terms of money options, when the amplifier has 4 channels or 6.
