Give your speakers the power they deserve

Rockford Fosgate's Prime Series R2-300X4 amplifier can power four speakers with 50 watts RMS each, so you'll hear your music clearly over the noises of the wind and road. You could also use this amp in bridged, 2-channel mode to power a couple of high-performance speakers or subs with 150 watts RMS each. High- and low-pass filters help you get maximum performance from the speakers in your vehicle.

Setting it up for optimum performance

Rockford Fosgate's C.L.E.A.N. technology (Calibrated Level Eliminates Audible Noise) setup system ensures your music will sound as clean and powerful as possible. It's a simple system to use — turn it up until the light shows red, then turn it down until the red light goes out. Speaker-level inputs let you hook this amp up to almost any system, even a factory stereo.

Product highlights:

  • 4-channel car amplifier
    • 50 watts RMS x 4 at 4 ohms
