How to choose a sound amplifier

When choosing, you first need to know what you are going to connect to it: one pair of speakers, two pairs, a subwoofer or all together? If you are going to connect only one pair of acoustics, then a two-channel amplifier will do, if two pairs of speakers are four-channel. To connect a subwoofer, in most cases either a single single-channel audio amplifier (monoblock), or five-channel, with a fifth channel, which has more power and is designed to connect the subwoofer. A subwoofer can also be connected to a two-channel or four-channel amplifier, but you must use a bridged connection.

The second selection criteria is the rated power per channel. To connect acoustics, with a rated power of 70 W, an amplifier with a power per channel of 60-70 W is needed. Ie, the power per channel must be slightly lower than the power of the connected acoustics, or equal to it.

Also, you should pay attention to additional features, such as the presence of high-level inputs, built-in crossover, remote bass controller, sound processor and the ability to work at 2 and 1 ohm.

A sound amplifier is one of the main components of a car sound system. Without it, it is impossible to unleash the full potential of acoustics. Without an amplifier, acoustics with a power of 70-80 W will not be able to work at full power from the radio. Sound amplifier can be bought on 130.com.ua with delivery to Kharkov, Odessa, Kiev and in Ukraine.

More information about the number of channels

The average model of the auto amplifier, as a rule, has two or four channels. Often there are models with an odd number of channels-three-channel and five-channel (one channel is usually used to connect a subwoofer).

More information about amplifier classes

As the name implies, class AB amplifiers are an attempt to combine the advantages of class A and B amplifiers, i.e. achieve high efficiency and an acceptable level of non-linear distortion. In order to get rid of the step transition when switching reinforcing elements, a cut-off angle of more than 90 degrees is used, i.e. The operating point is selected at the beginning of the linear portion of the current-voltage characteristic. Due to this, in the absence of a signal at the input, the amplifying elements are not locked, and some rest current flows through them, sometimes significant. Because of this, the efficiency is reduced and there is a minor problem of stabilizing the quiescent current, but nonlinear distortions are significantly reduced.

Class D includes the so-called "digital sound power amplifiers." In them, the size of the case and the value of the permissible current of the fuses are almost irrelevant, since the digital amplification elements are used in the assembly. The sound quality of such amplifiers directly depends on the price, so be careful when choosing.

More information about amplifier classes

Crossover. The so-called low pass filter, high pass filter and rarely a medium pass filter. A very useful feature if your car receiver does not have a built-in crossover.

Remote bass control. Enough convenient option that allows you to quickly and easily adjust the bass for any song.

High Level Inputs. Allow you to effortlessly connect the sound amplifier to the head unit on the acoustic output of the radio.
