Serious sound, made simple. The M5 amplifiers feature the next level of Element Ready™ design from Rockford Fosgate that’s built as rugged as the outdoor environment it’s used in.

Element Ready™: Purpose Built for the Marine Environment, Rockford’s Element Ready™ products are built to stand up to Water, Salt, and UV, making sure your amplifiers stand the test of time.

C.L.E.A.N.: Our Patented circuit with input and output clip indicators help match the source unit to the amplifier, which makes for easy set-up and optimizes musical output.

P.O.W.E.R. Supply: The unique P.O.W.E.R. supply continues to generate more than rated power as the voltage increases, giving you the output, you demand.

Rockford Fosgate amplifiers are known world-wide for producing more power than their ratings suggest. The M5 amplifiers are the first series based on new industry standard Dynamic Power ratings, bringing their conservative ratings to the forefront. Engineered from the ground up and purpose-built to deliver more output where you actually hear it, this is real dynamic power that performs not only on paper, but performance heard through the musical experience.

You’ll see two amplifier power ratings, the traditional Continuous Power output, and the new Dynamic Power output, both tested in accordance with the CTA-2006 specification. Consider Continuous Power as wattage developed on the test bench for comparison against other amplifiers in the same class, and Dynamic Power as real-world wattage when connected to a speaker load, listening to music. Either way you look at it, Rockford Fosgate is proving – once again – these amplifiers are powerful enough to drive any speaker or subwoofer you throw at them.

Element Ready™

All components are protected against harsh outdoor elements like Dust, UV, Temperature, Water, Corrosion & Vibration.


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

IPX6 Water Intrusion Rating

Water projected in powerful jets from any direction shall have no harmful effects.


MEHSA4 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.

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

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.

Balanced Differential Inputs

Differential inputs eliminate noise picked up by signal cables.

Constant Power

Constant Power is a patented circuit topology that provides instantaneous delivery of output power over varying impedance loads.

Punch EQ2

Onboard equalizer with up to +18dB @ 45Hz and/or up to +12dB boost at 12kHz.


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

CTA-2006 Compliant

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.


Class-BD amplifiers have 75-80% efficiency ratings vs. 20-60% efficiency ratings of traditional Class-A/B amplifiers.


This technology allows the amplifier to produce more power with less current draw from the vehicle's charging system.

Engineered In The USA
