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 Watt peak power output, the MS-AM504 will power either a pair of Fusion speakers plus a 10 subwoofer, or up to four pairs of speakers (with 2 speakers in parallel each channel at 2 Ohms), 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.


  • 500W peak power output to power up to eight speakers
  • Class-AB amplifier power efficient with less cross-over distortion
  • Conformal coated PCBs water resistant protection from salt air and moisture
  • FUTRANZ heat sink technology transfers heat more efficiently and provides more thermal stability with maximum component reliability
  • F.R.A.T (Fusion Regulated Amplifier Technology) provides enormous power output at low voltage
  • F.I.S.T (Fusion Intercooled Semi-Conductor Technology) clams down internal power switching to rapidly remove heat from all associated semi-conductors
  • 1 year limited Consumer Warranty
  • The Fusion AM Series marine amplifiers are the perfect complement to any Fusion marine stereo system
