Overview
The M2 750 Watt 5‑Channel Element Ready™ Amplifier (M2-750X5) is a full-range Class‑D marine amplifier delivering up to 750 watts total. Built for marine environments, it operates efficiently in stereo at 4Ω or 2Ω and supports 4Ω bridged/mono operation; the dedicated subwoofer channel can be used at 4Ω or 2Ω. Onboard features include C.L.E.A.N. gain circuitry, a P.O.W.E.R. Supply, integrated Punch EQ, balanced differential inputs, MEHSA 4 heat-sink design, CTA‑2006 complianc…
Best for
- Boats and watercraft exposed to sun and moisture
- Multi-channel systems that include both speakers and a powered subwoofer
- Users seeking an efficient, compact Class‑D amplifier with straightforward setup
- Installers and systems requiring CTA‑2006 compliant components
Key points
- Element Ready™ construction with UV-resistant protection and internal conformal coating for marine environments
- Full-range Class‑D design, 5 channels, 750W total power
- Operates as stereo at 4Ω or 2Ω; supports 4Ω bridged/mono; subwoofer channel configurable at 4Ω or 2Ω
- C.L.E.A.N. circuitry for simplified gain adjustment
- P.O.W.E.R. Supply increases available power as system voltage rises
- Integrated Punch EQ to correct acoustic deficiencies and deliver up to 3X the bass
Fit and use
Use the M2-750X5 in marine audio installations with compatible speakers and subwoofers. Its Class‑D efficiency helps reduce demand on the vessel electrical system. Verify speaker impedance and power handling when configuring stereo (4Ω/2Ω) or bridged (4Ω) modes, and consult the manufacturer specifications for exact power distribution and wiring details.
What to know
Element Ready™ construction combines UV-resistant materials and conformal-coated electronics to protect against marine exposure; it is designed for such environments but performance depends on correct placement and installation. Features like C.L.E.A.N., Punch EQ and the P.O.W.E.R. Supply allow tuning and help manage…

More info
Manufacturer details
Designed to withstand the elements, the R2-750X5 amplifier is an Element Ready™ 750 watt, full-range class-D model, capable of operating at 4Ω or 2Ω stereo, and 4Ω bridged/mono with a subwoofer channel that can be run at 4Ω or 2Ω. This amplifier is extremely efficient because of its class D technology which reduces demand on the electrical system. The amp also features C.L.E.A.N. circuitry to help you adjust your gain settings, a P.O.W.E.R. Supply that generates more power as voltage increases, and integrated Punch EQ that corrects for acoustic deficiencies while delivering up to 3X the bass.
Additional details
The M2 Series were developed for marine audio environments that feature UV resistant protection and special internal conformal coating that protect the electronics from water. It’s designed for those who want a reliable amplifier – with all the power and performance you’ve come to expect from Rockford Fosgate – at an economical price. Rockford Fosgate amplifiers are renowned world-wide for being “under rated,” easily surpassing all specifications, and most importantly, generating more power than their ratings. The latest generation of M2 Series amplifiers are also designed to be easy to setup and configure, making them perfect for use in any application.
