Overview

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.
