Product details
Five-channel Element Ready power
Rockford Fosgate rates the M2-750X5 at 50 watts x 4 plus 200 watts x 1 into 4 ohms, or 100 watts x 4 plus 350 watts x 1 into 2 ohms. Front channels bridge to 200 watts x 2 at 4 ohms for component sets when the sub channel runs separately. Class-D topology keeps the chassis compact while covering 20 Hz to 20 kHz for full-range marine and motorsports systems.

Crossovers and inputs
Independent front, rear, and sub crossovers offer 50 Hz to 250 Hz high-pass and low-pass filters at 12 dB/octave Butterworth. The sub channel adds a 15 Hz to 40 Hz infrasonic filter and 0 to +18 dB bass boost at 45 Hz. Low-level RCA and high-level Molex inputs are provided for front, rear, and sub. Input sensitivity spans 150 mV–4 V low-level and 450 mV–12 V high-level for factory or aftermarket sources.

Marine install notes
Element Ready construction targets water, salt, and UV exposure on boats and UTVs. Plan appropriate gauge power wire and a fuse at the battery per the manual. Speakers, subwoofers, and a remote bass knob (if used) are sold separately. Confirm the mounting location stays clear of standing water even though the amplifier is Element Ready for harsh outdoor duty.
