Shop Roswell marine amplifiers, including R1 Pro GaN (gallium nitride) amplifiers, R1 stackable marine amps and compact SD series amps with an IP66 rating. Choose mono subwoofer amplifiers or 2, 4, 6 and 8 channel boat amplifiers to power speakers, tower speakers and subwoofers. R1 Pro GaN amplifiers provide high output with lower power draw for longer battery runtime, and R1 amp spacers allow clean stacked installs. Add a Roswell marine amp wiring kit to complete your installation.
