ROCKFORD FOSGATE Prime 400 Watt Class-D 4-Channel Amplifier
The PRIME R400-4D is an ultra-efficient 4-channel amplifier producing 100 Watts into four channels at 2-Ohms. Run a 4-way full-range system or use it with components on the front channels with subwoofers on the rear.
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.
