Punch 500 Watt Mono Amplifier

The PBR500X1 is a 500 Watt amplifier with Boosted Rail Technology, allowing it to be compact and efficient while providing big power.

This amp is great for smaller stealth installations, motorcycles and recreational vehicles.


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

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.
