Prime Marine 750 Watt Class-D Mono Amplifier

The M750-1D is a 750 Watt mono high efficiency Class-D marine amp featuring a Marine grade PC Board, on-board Punch EQ, infrasonic filter, variable crossover and tri-state protection circuits.





The Prime M750-1D amplifier is a 750 Watt mono 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.
