Primed for Performance, the R2-750X5 is a 750 watt rated, full-range class-D amplifier capable of operating at 4Ω or 2Ω stereo with a mono subwoofer channel that can be run at 4Ω or 2Ω. The front/rear stereo channels can also be run at a 4Ω bridged/mono load. 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 dynamic power as voltage increases, and an integrated Punch EQ that corrects for acoustic deficiencies while delivering up to 3X the bass.
