R2-750X5

Prime 600 Watt 5-Channel Amplifier R2-750X5

Primed for Performance, the R2-750X5 amplifier is a 600 watt, full-range class-D, capable of operating at 4Ω or 2Ω stereo, and 4Ω bridged/mono with a subwoofer channel that can be run at 4Ω or 2Ω. This amplifier is extremely efficient because of its class D technology which reduces demand on the vehicles electrical system. The amp also features C.L.E.A.N. circuitry to help you adjust your gain settings, a P.O.W.E.R. Supply that generates more power as voltage increases, and integrated Punch EQ that corrects for acoustic deficiencies while delivering up to 3X the bass.

Overview

The Prime Series were developed for car audio fanatics that want a reliable amplifier – with all the power and performance you’ve come to expect from Rockford Fosgate – at an economical price. Rockford Fosgate amplifiers are renowned world-wide for being “under rated,” easily surpassing all specifications, and most importantly, generating more power than their ratings. The latest generation of Prime Series amplifiers are also designed to be easy to setup and configure, making them perfect for use with factory audio or custom aftermarket systems.
