Product Details

Rockford Fosgate Punch 300 Watt BRT Mono Amplifier, Model PBR300X1

The PBR300X1 is a mono 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. Great for motorcycles and recreational vehicles.
