The Prime R400-4D amplifier offers high efficiency through the implementation of its Class-D circuitry while being able to power a full-range system. This amplifier is optimized for 4-channel front/rear systems so you can run midrange/tweeters in the front doors/dash while running midrange/tweeters in the rear doors/deck. Match with a mono amplifier for subwoofers and you'll have a Rockford Fosgate system that any Car Audio Fanatic will envy.

This is an absolutely amazing buy for the money, quality, and power this amp puts out. I've had mine for about a year or so now, and it's never let me down.
