Rockford Fosgate designed Prime amps to deliver Power Output Without Excessive Regulation (POWER), which means they'll respond quickly to the peak demands that you may throw at your system. Your driver's seat will become your favorite place for listening when you add the clarity and impact of a Rockford Fosgate amp.

The R300-4 4-channel amp puts out 50 watts RMS per channel to your speaker system, or you can bridge it to supply 150 watts RMS to a pair of speakers or subs in 2-channel mode.
