    Prime 500 Watt Mono Amplifier


    Primed for Performance, the R2-500X1 amplifier is a 500 watt, class-D, capable of operating at 4Ω or 2Ω 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, and integrated Punch EQ that corrects for acoustic deficiencies while delivering up to 3X the bass. For subwoofers, a variable infrasonic filter and remote level control allows you to tune the bass for the desired level for the music.
