Best Car Multichannel Amplifiers Buying Guide

Before choosing the best car amplifier you should consider the following options:

1. Wattage Requirements: The first thing you should figure out is the right power amplifier for your system. Power is measured in Watts.

You can find the RMS Wattage of your speakers from the manufacturer. If you don’t have the information, you can make an approximation using the following formula:

2. Amplifier Wattage: You should not just pick the amplifier with the highest Wattage. You should also take other factors into accounts such as the impedance of the amplifier and the sensitivity of your speakers.

It is best to choose an amplifier that delivers between 20-50% of the RMS Wattage of your speakers. If you choose an amplifier that delivers more than that, you will end up with distorted sound.

3. Number of Channels: Your system may have one or two channels. Most car stereos have two channels and a bass booster.

A mono amplifier can drive one set of speakers. A stereo amplifier can drive two sets of speakers with a separation of highs and lows.

4. Class of Amplifier: Amplifiers are classified by their characteristics. They can be class A/B or class D.

Class D amplifiers are more efficient and produce less heat. But they are expensive and are usually used in high-end car stereos.

A/B class amplifiers are the most commonly used type. They are affordable and produce less heat.

5. Types of Amplifiers: Amplifiers can be classified by the following characteristics:

Monoblock Amplifiers: A single unit with two channels. These are ideal for stereos with only one subwoofer.

Stereo Amplifiers: Two separate units with a separation of highs and lows. These are ideal for stereos with two speakers.

Single Channel Amplifiers: One unit with one channel. These are ideal for stereos with one subwoofer and one speaker.

Combination Amplifiers: A unit that delivers both bass and treble. These are ideal for stereos with one subwoofer and one speaker.

6. Features: Amplifiers can have different features. Some of the most common ones are:

Input and Output Connectors: You should check the connectors to make sure they match your speakers and other audio components.
