Roswell R1 650.4 Marine Amplifier

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 4Ω, and are perfect for powering your R1 6.5" in-boat 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 PCB's and nickel-plated marine-grade wire terminals to ensure their quality.

For more than two decades, Roswell has been innovating, designing, and manufacturing industry-defining wake towers, board racks, boat speakers, and more. When Robert Oswell pioneered and patented the first shock absorbing tow rope pylon in his garage in 1998, what he ultimately envisioned was an industry in its infancy, and that meant innovation could thrive for decades to come. Driven by his passion for boating and watersports, from that Canadian garage he would ultimately launch a global company which has defined many of the marine products we all use and love today. The company has proudly introduced many industry-first products, including everything from the now patented foldable weight assist system in a tower, cam lock systems and spinning tower speakers.
