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.

Prime 750.1!!!! Yessir

This amp slams my 10in sub hard!!! Received the amp and has more watts then advertised! Love it and Rockford Fosgate has a customer going forward!!

750.1

Best bang for the buck I've seen in decades.Runs three 8 inch Sundown E8s with zero issue....Im an old-school PPI guy at heart,but I pulled out a PC1400 that is in great working order due to the Class D Rockford utterly embarrassing it in an A/B comparison...Very efficient,I needed an extra battery for the 1400,this 750 is running off the STOCK electrical, and it does not cause any voltage drop worth talking about....No gripes other that it being made in China,but meh,when can you do anymore...
