ROCKFORD FOSGATE Punch 300 Watt Mono Amplifier

$239.99 USD
PBR300X1

The Punch PBR300X1 is a 300 Watt mono amplifier designed for compact subwoofer systems. This efficient amp packs a Punch in motorcycles, ATVs and hybrid-electric vehicles without sucking a lot of juice from your electrical system.

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.

 

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