The RFBDL210624-08 Bundle Includes Two Rockford Fosgate P3D4-12 12" Punch P3 4-Ohm DVC Subwoofer and One R2-1200X1 Prime 1200 Watt Mono Amplifier. The P3D4-12 12-inch subwoofer is Rockford Fosgate's best performing Punch series subwoofer. The P3 subwoofers now feature anodized aluminum cones and dustcaps along with unique spider venting to keep the motor cooler than previous versions. These feature VAST technology to increase surface cone area up to 25% and a FlexFit basket for extreme installations. Best of all, a new hybrid stamp-cast basket offers the best of both worlds by providing super strength while minimizing weight and resonance. Primed for Performance, the R2-1200X1 is a 1200 watt, class-D amplifier, capable of operating at 4Ω, 2Ω or 1Ω 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.
