FUSION MS-AM504, 010-01500-00, 500 Watt, 4 Channel Amplifier, 2 Ohm Stable, Stainless Steel endcaps and base


The Fusion AM series marine amplifiers are purpose built for the marine environment. Boasting some of the most impressive environmental protection available, they deliver performance on the water like never before. With 4 channels and a 500 W peak power output, the MS-AM504 will power either a pair of Fusion speakers plus a 10 in subwoofer, or up to four pairs of speakers (with 2 speakers in parallel each channel at 2 Ohm), to spread the sound around your vessel. Incorporating heat tempered and conformal coated PCBs for maximum product life and gold-plated connectors for improved signal flow, the MS-AM504 reproduces clean and powerful audio with enough power to rock the boat.
