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.

M5 Amp Product Overview

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.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
