The R1 650.4 marine-grade amplifier, made by Roswell, is everything your boats audio system has always wanted. These stackable amplifiers utilize a 4-channel Class-D design, that puts out 100 watts RMS per channel at 4, and are perfect for powering your R1 6.5 marine speaker setup. Easily bridge & tune with the calibrated crossover controls. Because LEDs create lots of noise issues, this amp features differential RCA inputs for maximum noise rejection. The R1 650.4 is built with fully conformal-coated PCBs and nickel-plated marine-grade wire terminals to ensure their quality.
