SPECIFICATIONS

SUPPORT

The Prime M400-4D amplifier is a 400 Watt 4-channel high efficiency Class-D amplifier specifically designed for Marine and Powersport applications. The amplifier features a Marine grade PC Board, and the Class-D circuit topology is so efficient, it consumes much less current from your charging system over traditional Class-A/B amplifiers.

 

  • 12dB/octave Butterworth crossover
  • 2/4 channel input switch
  • 4 Gauge power/ground connectors
  • Cast aluminum heatsink
  • Top mounted controls
  • Marine grade 2-part epoxy coated PCB
  • On-board Punch EQ with +18dB boost @ 45Hz
  • Tri-stage protection covers thermal, over-current and short circuits.
