Manufacturer: Rockford Fosgate
SKU: P400X4
Call for best price
The Punch P400X4 is a 4-channel amplifier producing 100 Watts into all four channels at 2-Ohm. The P400X4 is perfect for a 4-way full-range system or a 3-way system having a front stage with subwoofers on the rear channels. The P400X4 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 P400X4 is an excellent amplifier choice for virtually any vehicle.

CE Compliant

This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).

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.

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

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.

Available Wiring Diagrams

Please consult your amplifier owner's manual for lowest recommended impedance.
