Buying Guide

Channel configuration

Choose a 2-channel amp for driving a pair of speakers or bridged sub use, or a 4-channel amp to power front and rear speakers without a processor

Amplifier class and efficiency

Class-D amps are compact and energy-efficient for cars, while Class-AB offers different tonal characteristics—use the class that matches your power and space constraints

Power ratings and matching

Match RMS power per channel to your speakers' continuous power ratings and consider bridged power specs if you plan to combine channels for a subwoofer

Input and output options

Look for low-level (RCA) inputs for clean signal from head units and speaker-level inputs if integrating without RCA outputs; check for speaker terminals that accept your wire gauge

Controls and features

Prioritize amps with adjustable gain, crossovers, and bass boost if you need tuning flexibility, especially for systems using multiple speaker types
