ROCKFORD FOSGATE P400X4

ROCKFORD FOSGATE

(P400X4) PUNCH 400 WATT 4-CHANNEL AMPLIFIER

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.

TECHNOLOGIES:

• CE Compliant:  This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).
• CTA-2006 Compliant:  Power ratings on Rockford Fosgate amplifiers conform to CTA-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.
• MEHSA^3:  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:  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.
