Rockford Fosgate P400X4 Punch 400 Watt 4 Channel Car Amplifier

Rockford Fosgate Punch P400X4 400W Punch Series 4-Channel Stereo Class AB Car Power Amplifier (P400X.4)

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.

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 stealth top-mounted control panel not only provides a sleek finished look to the amp but also protects the vital controls.

Our custom heat sink design uses high aluminum mass where it is needed most to maximize heat transfer from the output MOSFETS to the surrounding air, keeping the circuitry cool even under high power and output demand.

General Features:

  • Class-AB FullRange 2-Ohm Stable 4-Channel Amplifier
  • RMS Power Rating:
  • 4 ohms: 50 watts x 4 channel
  • 2 ohms: 100 watts x 4 channel
  • Bridged, 4 ohms: 200 watts x 2 channel
  • CEA-2006 Compliant Amplifier
  • Features C.L.E.A.N. Set-up with 10-step set-up procedure
  • w/ input/output clip detection and indicator LEDs
  • Pulse Width Modulated MOSFET power supply
  • LED power (blue) and protect (red) indicators
  • Stealth top-mounted control panel
  • Soft start turn-on
  • 4, 3, or 2 channel operation
  • Nickel-plated RCA level inputs
  • Nickel-plated captive C-clamp terminals
  • High-level input capable with Auto Turn-On circuit (RFIF2SW required, sold separately. Up to TWO adapters needed for this amplifier.)
  • 3-way protection circuitry (thermal, overload, and speaker short protection)
  • On-board differential inputs eliminate noise picked up by the signal cable
  • Integrated Trans•ana technology 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
  • MESHA3 reduces MOSFET temperatures, lowers distortion, increases durability, and prolongs the output device life span
  • DSM (Discrete Surface Mounted Components) utilize 1% tight-tolerances improving the efficiency of the circuit and lowering the operating temperature and potential for noise - similar to circuit boards designed by aerospace manufacturers
  • Built-in NOMAD is a "real-time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances
  • Cast aluminum convection heatsink with DTM (Dynamic Thermal Management) evenly distributes excess heat across the entire amplifier heatsink to efficiently keep the amplifier temperatures low
  • Input sensitivity: 150mV - 12V
  • Frequency Response: 20 - 20,000 Hz
  • Total Harmonic Distortion (THD): <1.0%
