M2-750X5

The Rockford Fosgate M2-750X5 is a high-performance 5-channel marine amplifier from the M2 series, designed specifically for demanding audio installations on boats and other recreational vehicles. Thanks to its efficient Class D technology, it delivers a total output of up to 750 watts RMS while maintaining low power consumption and a compact design.

Element Ready™ technology ensures enhanced resistance to moisture and harsh environmental conditions. The integrated C.L.E.A.N. technology allows for precise adjustment of input and output levels, while the innovative P.O.W.E.R. power supply can provide additional power as the supply voltage increases.

With the built-in Punch EQ bass boost, variable crossovers, and an adjustable infrasonic filter, the amplifier can be optimally tuned to different speaker and subwoofer configurations. Thanks to the high-level inputs with an automatic power-on function, integration into existing audio systems is also straightforward.
