Rockford Fosgate 800 Watt 4-Channel M5 Element Ready Amplifier

The M5-800X4 amplifier from Rockford Fosgate features Element Ready that’s built as tough as the outdoors. There's no need to set-up and tune the amp due to the PRESET switch functionality - making. The IPX6 rating is provided by splash guards on both ends and heavy-duty molded harnesses with integral sealing gaskets. The proprietary Class-AD technology allows the amplifier to produce more power with less current draw. Combining two superior amplifier power ratings maximizes the sound and performance when connected to speakers.


  • 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
  • Low Impedance Stability
  • Proprietary testing using RATS (Rockford Automated Testing System)
  • Proprietary Class-AD technology allows amplifier to produce more power with less current draw
  • Discrete Surface Mount technology utilizes 1% tight-tolerances for high efficiency and reduced cross-talk
  • MESHA 4 reduces MOSFET temps, lowers distortion, increases durability and prolongs device life span
  • Chassis Isolation from mounting points greatly reduces possible introduction of vehicle noise
  • Balanced Differential Inputs eliminates noise picked up by signal cables
  • Remote-Out feature when using high level inputs
