Rockford Fosgate Prime R2-500X4 500W Prime Series 4-Channel Full Range Class D Amplifier

Primed for performance, the R2-500X4 is a 500-watt, full-range Class-D amplifier capable of operating at 4Ω or 2Ω stereo and 4Ω bridged/mono. This amplifier is extremely efficient because of its Class-D technology which reduces demand on the vehicle's 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. Rockford Fosgate's R2 amplifiers are the building blocks for great audio systems, powerful enough to even DRIVE our Punch speakers and subwoofers. They have undergone an amazing upgrade by packing them with the latest features at an incredible value. Best of all, they are designed and engineered here in Tempe, Arizona.
