R1 650.4 4-Channel Marine Amplifier

The R1 650.4 marine-grade amplifier from Roswell, is everything a boat's audio system has always wanted. These stackable amplifiers utilize a 4-channel Class-D design that puts out 100 watts RMS per channel at 4Ω and is perfect for powering an R1 6.5″ marine speaker setup.

Easily bridge and 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.
