Automotive articles - sound amplifiers

Music allows you to comfortably go on long trips, but sometimes the sound quality of your favorite songs leaves much to be desired or we do not have enough power to fully immerse in the world of sounds. To do this, you need to know how to choose the sound amplifier, which you will have to purchase regardless of whether your car radio is good or not. After all, most devices can not provide loud sound without additional elements.

The external auto amplifier will allow you to sound better at all levels of volume: even at the highest levels. This element is mandatory if you want to connect a subwoofer that requires significantly more power than a standard radio.

The choice of the sound amplifier depends on the desired number of channels:

Single-channel: necessary to improve the volume of music on one channel. Most often such models are used for subwoofers.

Stereo: the speakers are connected via a stereo system. Such devices provide two or three channels, in the latter version you can use a subwoofer.

Four-channel - the base for creating high-quality sound, you can create an acoustic system "quadro".

Five-channel - an advanced version with the possibility of additional subwoofer connection.

It is possible to connect several amplifiers, but then pay attention to the parameters of the output channels, which may differ for different speakers.

When choosing the right model, pay attention to the following parameters:

Power is one of the determining factors, which you should pay attention to when choosing sound amplifier for auto. The value should match the acoustics of your car. If you select a too powerful device, then there is a risk that your speakers will not withstand this voltage and will burn. But too small a value will cause the distortion of the sound to be at a low volume.

The signal-to-noise ratio is especially important for high-frequency speakers. In general, the higher this figure is, the better.

The value of the nonlinear distortion - shows how the sound can be distorted. The lower this indicator, the better.

It is recommended to choose models with a metal casing, there must be cooling fins. Among the additional functions can be used the ability to mute the sound or equalizer. Some models are equipped with additional inputs. The crossover function allows you to adjust the frequencies for a specific speaker, thus obtaining a clean sound.
