Product details
Mono muscle for marine and UTV bass
Subs on the water or on the trail need an amp that shrugs off spray and dust. The M5-1000X1 is Rockford Fosgate’s Element Ready mono amplifier with an IPX6 rating and integrated harness seals. CTA-2006 continuous power is 500 watts × 1 at 4 ohms and 750 watts × 1 at 2 or 1 ohm. Dynamic PowerCube figures reach 1,000 watts at 1 ohm. Frequency response is focused from 30 Hz to 245 Hz for subwoofer duty.

Class-BD efficiency and CLEAN setup
Class-BD topology targets 75–80% efficiency over traditional Class A/B designs, so more of your charging system’s output becomes bass instead of heat. Patented Constant Power can boost output by up to 25% as impedance shifts. C.L.E.A.N. input and output clip LEDs take the guesswork out of gain setting, and Discrete Surface Mount construction tightens tolerances.

PRESET and integration
PRESET mode removes setup steps when the amp is paired with Rockford Fosgate UTV audio kits. Low-level and high-level inputs cover OEM and aftermarket sources, with remote-out on high-level. Plan charging capacity and wire gauge for a full 1,000-watt Class-BD load in a marine or powersports electrical system before you mount the chassis.
