The PM400X4 is perfect for 4-way front-stage/rear-fill or 3-way front-stage/subwoofer systems. Simply drop a pair of component speakers on the front channels and subs on the rear and BOOM - you got "The PUNCH." With its flexible design, the PM400X4 is an excellent amplifier choice for virtually any boat.

Element Ready™ - AmpsThese amplifiers are protected against Dust, UV, Corrosion, and feature Stainless hardware. |
DSMDSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature. | CEA-2006 CompliantPower ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings. |
CE CompliantThis product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).
| NOMADNOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances. | C.L.E.A.N. Set-UpC.L.E.A.N. (Calibrated Level Eliminates Audible Noise) is a patented circuit with in/out clip LEDs to help match a source to the amp and optimise output. |
DSMDSM utilises 1% tight-tolerances improving the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
| Engineered In The USAThese Avatars are a personal signature from the Rockford Fosgate team member(s) who designed and engineered this fanatic product. This statement illustrates our commitment to being Designed and Engineered in the U.S.A.

Balanced Differential InputsDifferential inputs eliminate noise picked up by signal cables. |
TRANS•anaTrans•ana is a Class A/B topology that simplifies the signal path of the amplifier allowing the signal to travel through the amplifier at a lower voltage. The result is greater reliability and exceptional sound quality. |
DTMDynamic Thermal Management evenly distributes excess heat across the entire amplifier heatsink. |
