Rockford Fosgate R750-1D Prime 750 Watt Class-D Mono Amplifier

The Prime R750-1D amplifier offers high efficiency through the implementation of its Class-D circuitry while delivering rich, full bass to any system. This amplifier is optimized for subwoofers with the implementation of an infrasonic filter to keep those ultra-low (inaudible) bass notes from damaging your subwoofer system. Match with a 4-channel stereo amplifier for your mids/highs and you'll have a Rockford Fosgate system that any Car Audio Fanatic will envy. 12dB/octave Butterworth crossover Infrasonic filter On-board Punch EQ with +18dB boost @ 45Hz Remote PLC (Punch Level Control) RCA pass-thru outputs Real time output and power supply thermal sensing Cast aluminum heatsink Top mounted controls 4 Gauge power/ground connectors MOSFET power supply Short circuit protection Muted turn on.
