Punch 400 Watt Mono Amplifier The Punch P400X1 is a mono amplifier capable of producing 400 Watts into a 2-Ohm load and is designed for medium to high-powered subwoofer applications. You can also use the P400X1 for multi-speaker center channel applications.

Product highlights:

  • full-range mono amplifier
  • frequency response: 20-20K Hz
  • 250 watts RMS x 1 at 4 ohms (400 watts RMS x 1 at 2 ohms)
  • CEA-2006 compliant


  • variable high- and low-pass filter filter (50-250 Hz, 12 dB/octave)
  • variable PEQ2 bass/treble boost (0-18 dB at 45 Hz and 0-14 dB at 12.5K Hz)
  • C.L.E.A.N. gain setup system includes test tone CD
  • test tones also available as MP3 download from Amazon On Demand, Rhapsody, Google Play, and Spotify, labeled “3sixty.3 setup disc” (Punch amps and the 3sixty.3 use the same test tone tracks for setup)
  • Class-AB amplifier design
  • Dynamic Thermal Management and MEHSA MOSFET cooling systems
  • MOSFET power and output stages
  • preamp inputs and outputs
  • speaker-level inputs (speaker wire to RCA adapter required)
  • signal-sensing turn-on with speaker-level inputs eliminate need for remote turn-on lead

More Info:

  • optional PLC2 wired remote level control with clip light available
  • 4-gauge power and ground leads and an 60-amp fuse recommended — wiring and hardware not included with amplifier
  • no onboard fuses — when installing multiple amps in a system, an additional 60-amp in-line fuse between the distribution block and the amplifier is recommended
  • 9-15/16″W x 2-7/16″H x 8-13/16″D
