The Punch PBR300X1 is a 300 Watt mono car audio amplifier designed for compact subwoofer systems. This efficient amp packs a Punch in truck, sub-compact, electric, and hybrid vehicles without sucking a lot of juice from your electrical system.
The PBR300X1 is a mono car audio amplifier designed for a subwoofer system that requires little space. The BRT (Boosted Rail Technology) is an ultra efficient design that doesn't even use a switching power supply to generate its 300 Watts of power! The BRT also has a variable hi-level DC offset turn-on circuit for easy installation into any OEM system.
