Buyer’s Guide

Here are a few factors you should keep in mind when looking for a good 4 channel amp.

The overall power and power per unit

Instead of two, the amp is using four channels. So, it’s evident that it needs more power. The overall power and per channel power both should be high. 50 watts is a minimum requirement for power per channel. You can also try for 75 watts per channel if you really like feeling the music.

Class AB or D

AB-type 4 channel amps are the traditional models. These are bulkier with simpler designs. However, their sound quality is way better than D models. On the other hand, D amps have a more modern design and are more compact and portable. Although they sound good, they don’t sound as good as the AB models. Further, AB amps are cheaper.

Sound Quality

You don’t always have to listen to the amp to tell the quality. In fact, there are some quantitative factors helping you determine how good the sound quality is. These are:

The Filter: You’ll find a high pass and low pass filter in the amp. Each has its forte. High pass filters are better for full-range speaker sounds and similar sounds and low pass ones are for bass and similar sounds. You see, high spreads more while low doesn’t.

Signal to Noise Ratio (SNR): The more the value of SNR, the less noise in the amp. So the sound will be clearer. Decibels are used to calculate it.

Total Harmonic Distortion (THD): This means the amount of distortion you may face. The lower the value the better as the distortion will be low as well. You will usually see it measured in percentage.

Design Quality

This is where you consider the circuit board design, the internal connections, the quality of the materials, and so forth. In fact, this won’t only affect the durability of the amp but also the quality of the sound.  

Closing Thoughts

In conclusion, you will find many amps that are of top quality and value. However, it may be hard to find the best 4 channel amp for sound quality that fits your speaker or head perfectly. Therefore, make sure you find a compatible one.
