M2 300 Watt 4-Channel Element Ready™ Amplifier

Designed to withstand the elements, the M2-300X4 Element Ready™ amplifier is a 300 watt, full-range class-D model, capable of operating at 4Ω or 2Ω stereo, and 4Ω bridged/mono.





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.


  • Element Ready: built to stand up to the marine environment
  • C.L.E.A.N.: for easy setup and optimized output
  • P.O.W.E.R. supply: generates more power as voltage increases

CE Compliant

This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).

C.L.E.A.N. Set-Up

Patented circuit with in/out clip LEDs to help match a source to amp and optimize output.

Balanced Differential Inputs

Differential inputs eliminate noise picked up by signal cables.


MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.

CEA-2006 Compliant

Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.

Element Ready™ - Amps

These amplifiers are protected against Dust, UV, Corrosion, and feature Stainless hardware.


Power supply circuit design that allows the amplifier to increase output power as voltage increases.

Class D

High efficiency amplifier design that reduces current consumption from the charging system.


NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.

Rollback Protection

During demanding musical conditions, the amplifier can dynamically reduce demand to prevent stress on the output devices.
