Rockford Fosgate Punch PBR300x4

The Rockford Fosgate Punch PBR300X4 4-channel amplifier uses Rockford Fosgate's patented BRT (Boosted Rail Technology) for an extremely efficient design that does not require a switching power supply to generate the rated power. This allows the enclosure to be much smaller than conventional amplifiers. The BRT also features a variable high-level DC offset circuit for easy integration into any OEM system. It is ideal for smaller stealth installations as well as motorcycles and motorhomes.
