Car Amplifier Buying Guide

A comprehensive guide that will give you all the information you need on how to buy mobile amplifiers.
Getting Started
Amplifiers for cars can provide clean and clear sound for all sorts of volume levels. There are three types of amplifiers: mono car amplifiers, two-channel car amplifiers and multi-channel car amplifiers.
Types
Mono Car Amplifier
A mono car amplifier is designed for low-frequency reproduction and features built-in bass boost and low-pass filters. The best choice would be a class D mono amplifier, because they produce less heat, draw less current, and are more efficient unlike conventional amplifier designs.

Two-Channel Car Amplifier
A Two-Channel Car Amplifier is used for full-range and or component speaker systems. When using these types of amplifiers, they must have high-pass filters.

Five and Six - Channel Amplifier
Five and Six - Channel Amplifiers can be used for vehicle speakers located in the front, rear, and or the subwoofer of the whole system.

Multi-Channel Amplifiers
Multi-Channel Amplifiers can be used for full-range speakers and or subwoofers. When purchasing an amplifier, you should consider the level of power you want the unit to have.
Power Ratings
There are two types of power ratings: Root Mean Square Power (RMS) and Peak Power.

RMS Power
RMS Power measures the amount of continuous power a car amplifier uses to deliver the power to your speakers. Make sure that the power of your amplifier matches the power of your speakers and subwoofer. If the RMS power of your amplifier is too powerful it can damage your speakers.
Peak Power
Peak Power is always higher then RMS power. Peak power indicates how many watts a car amplifier has available for short and sudden increases in sound.
