The Punch PBR500X1 uses our patented BRT (Boosted Rail Technology) for an ultra efficient design that does not use a switching power supply to generate its rated power. This allows the chassis design to be much smaller than traditional sized amplifiers. The BRT also has a variable hi-level DC offset turn-on circuit for easy installation into any OEM system. It is great for smaller stealth installations, as well as for motorcycles and recreational vehicles.

  • Variable 4-6 volt hi level DC offset voltage input turn-on control
  • Ultra compact chassis
  • High level inputs
  • MOSFET output stage
  • 12dB/octave Butterworth crossover
  • 1 Year Warranty
