Rockford Fosgate PM400X4, Punch Series 4 Channel Marine Amplifier
The PM400X4 is a 400 Watt 4-channel amplifier with high dynamic power using Class-a/b technology and a conformal coated pc board designed for motorsport and marine applications.
DTM
Dynamic Thermal Management evenly distributes excess heat across entire amplifier heatsink.
TRANS•ana
Trans•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.
CEA-2006 Compliant
Power 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.
DSM
DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
CE Compliant
This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).
Balanced Differential Inputs
Differential inputs eliminate noise picked up by signal cables.
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 vehicle.
Element Readyâ - Amps
These amplifiers are protected against Dust, UV, Corrosion, and feature Stainless hardware.
MEHSA
MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.
NOMAD
NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.
Engineered In The USA
These 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.
