Rockford Fosgate performance in a small package. The Prime Series R300X4 4-channel amp can drive your speakers with 50 watts RMS each, so you’ll really feel your tunes rockin’. Or, you could switch the R300X4 to 2-channel mode to run a couple of subs with 150 watts RMS each — when you buy a bigger amp for your subs, later on, you can still use this 4-channel to drive all your speakers. Smart move.
You can use the high- and low-pass filters and Rockford Fosgate’s famous Punch boost to get maximum performance from the speakers in your vehicle. And speaker-level inputs let you hook this amp up to almost any system, even a factory stereo.
Rugged performance and value
The R300X4’s heavy cast-aluminum chassis efficiently draws damaging heat away from its internal components, ensuring reliable, long-term play. The amp’s built-in sensors keep track of the output current and power supply temperature, ensuring that plunging speaker impedances (they change constantly during play) or even a short circuit won’t hurt anything. Your driver’s seat will become your favorite place for listening to music once this Prime amp goes to work.
