Prime 300 Watt 4-Channel AmplifierR2-300X4

Primed for Performance, the R2-300X4 is a 300 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 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.
