ROCKFORD FOSGATE Punch 300 Watt 2-Channel Amplifier

The PBR300X2 is a 300 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.

The Punch PBR300X2 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
