RP-150.4ABM | 4-Channel Marine Amplifier



Skar Audio designed the RP marine series specifically for marine and powersport applications. The full-range RP-150.4ABM is the perfect solution for anyone seeking excellence on the open water. Capable of powering multiple sets of component, pro audio, or coaxial speakers, it packs the power that will allow your speakers to come alive. This extremely efficient, Class A/B, 4-channel, MOSFET amplifier is fully marinized with a water/rust proof coating on the PCB and mechanical casing. The RP-150.4ABM is conservatively rated at 1000 Watts RMS and achieves total amplifier efficiencies over 65%. Versatility is this amplifier's middle name, with an array of adjustable user controls such as the gain, LPF, HPF, crossover, and bass eq. Featuring a high-speed MOSFET power supply, 4-way protection circuitry, advanced electronics, and other internal high quality components, the RP-150.4ABM shines when compared to anything in it's class when it comes to power and reliability. The class A/B circuitry equipped in this amplifier allow it to reproduce extremely clean output, for the best possible sound on your boat.
