PBR500X1

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.
