FAQs

Q: How many channels do I need on a car amplifier?

It depends on how many speakers you want to power. A single-channel is ideal for a subwoofer only, while a two-channel amplifier can normally push two speakers and a subwoofer. Four-channel amplifiers are versatile because they can power a full speaker system and subwoofer.

Q: What does bridgeable mean?

This means that two channels can be connected to power a single speaker in order to produce more power. Most amplifiers have this feature, and some also have bass boost or crossover features that can be used on two out of the four channels.

Q: What is signal-to-noise (SNR) ratio?

Rated in decibels, signal-to-noise ratio is a way to compare the amount of audio signal an amplifier has against the amount of internal electrical noise it has. Good amplifiers have an SNR of 90dB and above.

We went with the Rockford Fosgate Prime 4-Channel Amplifier as the best four-channel car amplifier. It’s a high-quality compact amplifier that provides clear, crisp and loud sound. For a great amplifier at a better price, consider the Planet Audio 4-Channel Car Amplifier.
