The amplifier of a sound: on a car with a breeze and music!

Long gone are the times when, sitting down in the car's interior, you must prepare for hours to listen to the withering noise of the engine or the crackle of radio interference. Modern cars are equipped with stereo systems, which, due to the richness of acoustic effects, can compete with concert halls. "Reinforcements" are connected to them so powerful that you can learn about the approach of the machine long before it appears in the zone of visibility.

Let's talk about amplifiers

About what kind of sound amplifier is better and which model will suit its audio system, any driver seriously decides to equip his saloon with high-quality stereo equipment. What should I look for in resolving the issue?

- Dimensions. The driver must accurately understand exactly where he will place his sound amplifier, and to choose the technique should be based on the specified parameters. Otherwise, an unpleasant situation may arise when the device is purchased, but there is simply no place to store it. Those. The first rule is the harmony between the dimensions of the free space in the cabin and the dimensions of the amplifier.

- Device class. Classification begins, as usual, with letters A:

1. Class A. The related sound amplifier does not fit its functional role. For devices of this type, low-frequency distortions, a weak sound are characteristic, as a result, in order to hear music when the engine is running at full speed, the volume should be put almost to the maximum. In addition, this sound amplifier is rapidly heated due to the high energy consumption. This does not add vitality to the device itself, nor to the machine battery.
2. Class B devices. They are much better than the previous one in terms of technical parameters, quality of transmission of sound signals and thermal stability.
3. AB class. The sound power amplifier related to it is the average statistical power between classes A and B in terms of device parameters. Most often they are found in cars and the market of electrical engineering is represented by their wide choice.
4. Class D, in another way - digital signal amplification. In the past, devices operating at low frequencies were characterized in this way . At the present time, this is the broadband car audio amplifier . True, the quality of his work is somewhat inferior to the previous one. Therefore, today AB class is more common than others.

Channels for connection

Modern audio systems for cars are quite complex. If a couple of decades ago, the driver mounted only two speakers in the salon, then the current "stereo centers" could well compete with fancy home cinema systems. To date, manufacturers produce amplifiers with channels from one to six. Traditional is considered a two-channel device - the number recorded on standard CDs. What are the most frequent connection schemes? - "Back / front". Amplifier for 4 channels, type of sound - "volumetric". Minus circuits - the main richness of the sound remains in the background, and for low frequencies you need a subwoofer.

- "Reinforcement" with the scheme "front and subwoofer". Such are common among motorists. Easy to operate, they are standard in terms of quality. The sound is reproduced quite nicely. Channels from 3 to 4 or the "bridge", which connects two into one channel.

- Multimedia scheme for a cinema in a car.

The most suitable option is an amplifier with two channels, if it is possible to install it. More economical in terms of money options, when the amplifier has 4 channels or 6.
