2-Channel and 3-Channel Car Amplifiers Compared
A 2-channel amp powers one pair of speakers, or bridges to one channel for a small sub. The Pioneer GM-A3702 makes 60 W x 2 at 4 ohms and takes RCA or speaker-level input with auto turn-on, so it can work with a factory radio.
When a 2-channel or 3-channel amp fits
A 2-channel amp is the simple choice for one pair of speakers, like the front doors, or for one small sub when bridged. A 3-channel amp runs a pair of speakers and a sub from one chassis. For four speakers, see our 4-channel amp comparison, and for four speakers plus a sub, our 5-channel amp comparison.
Every amp here is on our listings. We install amps in our own bay at 22025 S Avalon Blvd Ste A in Carson.
Side by side
This table is built only from our own product listings. Where a listing does not state a spec, the cell says so instead of guessing.
Power is RMS as each listing states it. Bridged means the two channels combine into one, which is how a 2-channel amp drives a single sub.

Car Subwoofer Buying Guide: Sub, Box, Amp and Wiring for Your Ride
The right sub setup depends on three things: how much space you can give up, how hard you want it to hit, and what radio you are keeping. Small space and a factory radio usually means a powered sub.
