Your boat is a home away from home — and it should be able to play audio like home, too. Infinity marine amplifiers have the power for high-performance sound in a case that fits the small confines of most watercraft. This 5-channel Class D amplifier can boost the fronts, rears and subwoofer of a 4.1 speaker system. The 2-ohm front/back channel produces 65 watts of regular RMS power with an additional 500 watts through the subwoofer channel. Surge capabilities have you covered for up to 1,800 total watts. If you only have front speakers, bridge the main outputs for a 3-channel setup.
Craft the ideal marine audio system with the heavy-duty construction and flexible options of an Infinity M4555A boat amplifier. It has a high-level input adapter, bass boost and variable adjustment crossovers to squeeze out every decibel of clean sound. Three 30A ATO fuses are included along with speaker-to-RCA adapters and other installation accessories. These marine amplifiers are also well-suited for off-roading and areas with frequent harsh weather. We are an authorized Infinity dealer with free shipping and lifetime tech support on all purchases.
Infinity Marine amplifiers feature a slim chassis and a small footprint to allow for installation in tight spaces.
