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.
Thanks! You're on the list!
Overview
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.

Technologies
These amplifiers are protected against Dust, UV, Corrosion, and feature Stainless hardware.
Power ratings on Rockford Fosgate amplifiers conform to CTA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.
A full-range version of the Class-D topology which is a high efficiency amplifier design that reduces current consumption from the charging system.
Power supply circuit design that allows the amplifier to increase output power as voltage increases.
C.L.E.A.N. (Calibrated Level Eliminates Audible Noise) is a patented circuit with in/out clip LEDs to help match a source to amp and optimize output.
Differential inputs eliminate noise picked up by signal cables.
MEHSA4 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.
NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.
During demanding musical conditions, the amplifier can dynamically reduce demand to prevent stress on the output devices.
This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).
