Product Details

Rockford Fosgate Punch Marine 400 Watt 2-Channel Amplifier - PM400X2

The PM400X2 is a 400 Watt 2-channel amplifier with high dynamic power using Class-a/b technology and a conformal coated pc board designed for motorsport and marine applications.


  • High level input capable with Auto Turn-On circuit
  • RCA pass-thru outputs
  • Features C.L.E.A.N. Set-up
  • Optional remote Punch Level Control (PLC2) ready (w/ input clip indicator)
  • 12dB/octave Butterworth crossover
  • On-board Punch EQ with +18dB boost @ 45Hz
  • Muted turn on
  • Stealth top mounted control panel
  • Cast aluminum heatsink
  • Short circuit protection
  • Over current protection
  • Marine grade two part epoxy coating on circuit boards
  • Marine grade stainless steel hardware


  • 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.
  • 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.
  • CE Compliant
    This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).
  • Element Ready™ - Amps
    These amplifiers are protected against Dust, UV, Corrosion, and feature Stainless hardware.
  • Balanced Differential Inputs
    Differential inputs eliminate noise picked up by signal cables.
  • DTM
    Dynamic Thermal Management evenly distributes excess heat across entire amplifier heatsink.
  • DSM
    DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
  • MEHSA3
    MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.
    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.
  • C.L.E.A.N. Set-Up
    Patented circuit with in/out clip LEDs to help match a source to amp and optimize output.
