What is a Car Audio Amplifier

It is a real pleasure to listen to your favorite music while driving. Unfortunately, a standard car sound system does not always provide a fine-sounding music reproduction. That is why you should consider purchasing an amplifier for your car. A car audio amplifier is a device that amplifies an incoming sound signal to the level suitable for you. A capacity of such car sound amplifiers usually varies from 10 Watts to several thousand Watts per channel. You can boost both your speakers and subwoofer audio output.

Pre-installed car speakers are very often of rather poor quality, so we recommend you to look through our car speakers review, to choose the device with the desired characteristics. If you are looking for a quality car subwoofer, you will find one here.

What Features to Compare

The first thing to draw your attention to is the Number of Channels of the car audio amplifier. There are two kinds of car sound amplifiers: monoblocks that are bridgeable to a subwoofer, and multilink devices that support up to 8 channels. If you need to boost the sound quality of two speakers, you should consider purchasing an amplifier with 2 channels. If you have a car with a front/rear sound system, a 4-channel device will be perfect. This modification also suits for bridging 2 speakers and a subwoofer. A 6-channel device is a right choice for the owners of 5.1 acoustics.

The next important tip is a car audio amplifier's Power. Choosing car audio amplifiers, you should consider the power of the speakers in your car. Manufacturers tend to overstate the total power, showing its maximum value. That is why you should put your attention to the rated power that entirely depends on the system load. The power of speakers should relate to the Amp capacity as 1 to 1.6. This way, your car audio amplifier will provide the highest sound quality, using 70% of its power, and your sound system will use 90%.

One more characteristic to consider is the Output Signal Quality which depends on a signal/noise ratio and a total nonlinear distortion. The latter registers the work of a car sound amplifier (depending on how its operating modes change) and shows the sound distortion. The lower this index is, the clearer the sound is. The most up-to-date devices have a total nonlinear distortion index below 1%. A signal/noise ratio represents a signal strength to noise power correlation. This is a very important feature if you are purchasing the amp for a truly amazing sound quality. In general, we recommend you to choose a model with a signal/noise ratio of 100 dB or higher. 

The last but still very important thing you should pay your attention to while choosing a car audio amplifier is its Additional Features. Among them, there is an equalizer to adjust the sound frequency. A fitted crossover filter control is used for correcting distortions in all diapasons. Low-level inputs will let you connect the amplifier directly to your audio playback equipment. High-level inputs are used to connect your car audio amplifier to the speakers. It is worth noting that there are models with a remote subwoofer level control that allows users to adjust low frequencies to the tracks in real time.
