ROCKFORD FOSGATE R400-4D - 4-channel amplifier - PRIME series

Manual 

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.
