Description


Rockford Fosgate brand icon

Authorized dealer

  • Punch Series Monoblock Class AB Car Amplifier
  • RMS Power Rating:
    • 4 ohm: 200 watts x 1 chan.
    • 2 ohm: 400 watts x 1 chan.
  • 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 0-12 dB bass boost at 12 kHz depending on crossover selection)
  • On-board differential inputs eliminates noise picked up by the signal cable
  • 2/1 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
  • 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 evenly distributes excess heat across entire amplifier heatsink
  • 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)
  • CEA-2006 compliant amplifier
  • Frequency response: 20-20,000 Hz

Sweet

This amp is great. I have had it for six months without a flaw. It is very compact and sounds awesome no matter what I am listening to. Sonic Electronix had the best deal by far so I would recommend them for all of your electronic needs.

Great Amp

I replaced a terminater 1200w amp with this one because the terminater was overheating frequently. I am totally satisfied. Sound is crisp and clear. The thump my 2x 12" subs make is incredible.
