Audio power amplifiers for cars: helping to make the right choice

The car has long been not used only as a means of transportation. Some have to spend in it most of the day, or even stay overnight, for example, if you go on a long trip. Accordingly, the requirements for comfort are increasing. One way to improve this parameter is to install a power amplifier. As a result, you get the opportunity to listen to music at high volume with high-quality playback.

A car amplifier is one of the main elements of an audio system. It receives a signal from the linear output of the low-level car stereo and transmits a current with the necessary level to operate the speakers.

Device Types

Standardly, the main range of power amplifiers is divided into three groups:

mono-for one speaker;
two-channel-one subwoofer and two speakers;
Four channel-two subwoofers and four speakers.

There are also three-channel, five-channel and six-channel audio amplifiers, but they are not so popular among motorists.

This is a conditional division. To choose a really high-quality model, you need to focus not on its class, which will tell a little more about the selected device:

Class "A": ensure smooth playback, but are not very efficient. Efficiency level-up to 30%. An illustrative example: with a consumption of 100 watts, such an amplifier will produce a sound of up to 30 watts. Where does the rest of the energy go? It dissolves somewhere in electrical networks.
Class "B": differ in power up to 60 W., but they cannot boast of high quality playback.
Class "C": have a high efficiency-up to 75%. However, we observe that the higher this parameter, the more audible noise. It is not recommended to use such models for Hi-Fi audio systems.
Class "D". Modern models are distinguished by the possibility of digital signal processing. Another advantage is the compact design.
Class "AB": combine the advantages of A and B class. In the end, we got good efficiency and a clear signal.

Pay attention to the presence of a low-pass filter. Such parameters allow you to get good bass, and the subwoofer will work without strain at high volume. The presence of a high-pass filter provides improved sound.

What to look for when choosing

To focus only on the class or type of power amplifier is possible only if you are generally unpretentious to the sound. For connoisseurs of truly high-quality sound, it is recommended to consider the following parameters:

Power is one of the most significant factors of choice. Here consider, with what load it will be necessary to handle the amplifier. The power of the device must match the acoustics power: if the parameter is larger, that is, the risk of burning the speakers, and if it is less, the playback will be distorted. Take into account exactly the nominal rate, not the maximum.
The ratio of signal to noise is especially important if the device is intended for midbass, mid-range and tweeter speakers. In general, one rule applies to all models: the higher the indicator, the better.
Connectors: must be protected on all sides, the bounding walls must be close to the contacts, the dimensions of the contacts must cope with the recommended load of the amplifier.

The crossover function allows you to use the device universally, for example, to cut off low frequencies for tweeters, and high frequencies for midbass. Additional features may include: equalizer, additional outputs.
