Power Handling:

  • 75W RMS x 4 @ 4 Ohms
  • 150W RMS x 4 @ 2 Ohms
  • 300W RMS x 2 [Bridged] @ 4 Ohms

General Features:

  • Punch Series 4-Channel Class AB Car Amplifier
  • 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 or 0-14 dB bass boost at 12 kHz depending on crossover selection)
  • On-board differential inputs eliminates noise picked up by the signal cable
  • 4/3/2 or Mono channel operation
  • 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
  • RCA Pass-thru outputs
  • 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 efficiency of the circuit and lowers 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 entire amplifier heatsink to efficiently keep the amplifier temperatures low
  • Nickel-plated RCA level inputs
  • Nickel-plated captive C-clamp terminals
  • Variable high-pass filter (50-250 Hz, Butterworth, 12 dB/octave)
  • Variable low-pass filter (50-250 Hz, Butterworth, 12 dB/octave)
  • CEA-2006 compliant amplifier
  • Frequency response: 20-20000 Hz
  • Dimensions: 13-5/16"L x 7-3/4"W x 2-3/8"H
