500W RMS Punch Series 4-Channel Amplifier
Rockford Fosgate P500-4
  • Punch Series 4-Channel Class AB Car Amplifier

  • RMS Power Rating:

    • 4 ohms: 60 watts x 4 chan.

    • 2 ohms: 125 watts x 2 chan.

    • Bridged, 4 ohms: 250 watts x 2 chan.



  • Dynamic Rockford Power Output: 726 watts

  • MOSFET power supply

  • Remote bass level input (remote level control sold separately)

  • LED power, thermal, and protect indicators

  • Tuned bass EQ (0 - 18 dB bass boost at 45 Hz)

  • On-board differential inputs eliminates noise picked up by the signal cable

  • DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature

  • 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

  • Featured custom designed TO-247 MOSFETs have 60% more metal tab area providing more power handling capacity, lower impedance and improved heat dissipation over traditional TO-220 MOSFETs found in most competitor's amps

  • Built in NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances

  • Cast aluminum heatsink allows for a high performance energy tolerance

  • Dynamic Thermal Management evenly distributes excess heat across entire amplifier heatsink

  • 4/2 channel operation for additional adjustments

  • Heavy duty aluminum alloy heatsink or High-density split-dome convection heat sink for extreme heat dissipation

  • Nickel-plated RCA level inputs

  • Nickel-plated screw terminals

  • Variable high-pass filter (50-500 Hz, 12 dB/octave)

  • Variable low-pass filter (50-500 Hz, 12 dB/octave)

  • Frequency response: 20-20,000 Hz

  • CEA-2006 compliant amplifier

  • Dimensions: 13-1/64"L x 7-5/8"W x 2-1/4"H
