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 2 channels and a 400 Watt peak power output, the MS-AM402 will drive up to two subwoofers, an extra pair of speakers, or even 4 speakers (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-AM402 reproduces clean and powerful audio with enough power to rock the boat.


  • 400W peak power output to power up to four 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) – clamps 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.
