Rockford Fosgate 800 Watt 4-Channel M5 Element Ready Amplifier

The M5-800X4 amplifier features Element Ready design from Rockford Fosgate that’s built as rugged as the outdoor environment. The IPX6 rating is provided by splash guards on both ends and heavy-duty molded harnesses with integral sealing gaskets. A new PRESET switch - for use with Rockford Fosgate UTV / Side-by-Side / SxS audio kits - eliminates the need to set-up and tune the amp for the best experience possible. Built on the popular TM series, M5 amplifiers feature the same great technologies like Constant Power, Class-AD and C.L.E.A.N.

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.


  • Element Ready design with integrated harness and panel seals
  • PRESET removes the need to set-up and tune the amp when used with Rockford Fosgate UTV audio kits
  • C.L.E.A.N. input/output clip detection and indicator LEDs
  • Constant Power provides instantaneous delivery of output over varying impedance loads
  • Top mounted control panel with Element Ready smoked lens cover
