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



In-store

The PRIME R750-1D is an ultra-efficient mono amplifier that can produce 750 Watts into a 1-Ohm load without taxing the electrical system. The frequency response of the R750-1D is optimized exclusively for use with subwoofers.

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.
