Every car audio system needs to have an amplifier – and that’s a fact.

There are several types of amplifiers that you can find in the market today; this includes mono car amplifier, a two-channel amplifier, and a multi-channel amplifier such as 4-channel and or 5-channel amplifier.

If you are currently looking for an amp that can power-up 2 pairs of speakers, you need a 4-channel amp. To help find the best one, here are the top features that you should check-out.

1.    Best rated Signal-to-Noise Ratio (SNR)

An amplifier with a good sound quality must be rated at around 90 dB and above for its SNR; the SNR is a ratio of signal power to the noise power, which is often rated in decibel (dB). According to the experts, the higher the number, the better the specification; this means that an amp with higher SNR has better signal than noise. So, if you are looking for the best 4-channel amp in the market today, it is essential to take note on the amp’s SNR rating because a well-designed and manufactured amp can keep a low noise but with the high music signal.

2.    The quality of design

Another feature to look at, if you are looking for the best 4-channel amp, is the quality of its design. A great sounding 4-channel amp must have well-designed circuit boards and quality components. Channel amps with quality design are well-detailed and well-engineered than those cheap 4-channel amplifiers that you can find in the market today.

Here are a few examples of a well-designed amp that guarantees a great quality sound:

•    Quality made amplifiers have thicker and better PCBs (printed circuit boards)
•    The SMT components (surface-mount technology) are shorter and have smaller paths
•    Designed with low-noise parts and propriety circuits, which helps enhance the quality of sound.

There are a few of the current top options in the market today that follows a higher standard when designing and manufacturing amplifier; so, make sure to read reviews on the 4-channel amp you are planning to purchase.

3.    Compliant to Amplifier Power Standard

The standard implies that the amplifier you are about to purchase is guaranteed designed and manufactured with definite specifications and RMS power ratings.
