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.
Whether you're looking to drive high frequency component speakers or low frequency subwoofers, the PM400X2 has the power and flexibility you need to put some serious PUNCH in your vehicle. The power available from such a small amp means it's a great match for a 2-ohm DVC subwoofer or pair of 8-ohm SVC subwoofers.

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.
Element Ready™ - Amps
These amplifiers are protected against Dust, UV, Corrosion, and feature Stainless hardware.
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.
Balanced Differential Inputs
Differential inputs eliminate noise picked up by signal cables.
Dynamic Thermal Management evenly distributes excess heat across entire amplifier heatsink.
DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
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.
C.L.E.A.N. (Calibrated Level Eliminates Audible Noise) is a patented circuit with in/out clip LEDs to help match a source to amp and optimize output.
