This Punch Class BR amplifier uses Boosted Rail (BR) amp technology to generate so much power from such a tiny case, with capacitors and high-speed circuitry that boost the amp’s power supply voltage when needed, so it can handle musical peaks without missing a beat. Rockford Fosgate uses this new technology to create a remarkable amp that fits almost anywhere and delivers powerful sound.

The amp also features speaker-level inputs with signal-sensing turn-on, allowing you to connect into almost any system without having to run a turn-on lead back to the receiver. An extruded aluminum heat sink combines with Rockford Fosgate’s heat management technology to make sure your tunes keep rockin’ — even when you’re playing loud.
