Rockford Fosgate Punch PBR300X2 2-Channel Amplifier

The Rockford Fosgate Punch PBR300X2 is a 2-channel amplifier delivering 300 Watts total in a remarkably compact chassis, engineered for tight installs and OEM integrations. It uses Boosted Rail Technology (BRT) to reach its rated power without a traditional switching power supply, enabling a smaller footprint without compromising performance.

• Ultra compact chassis: A small form factor makes it easier to mount in cramped dash, under-seat, or trunk areas where space is at a premium.
• Boosted Rail Technology (BRT): Non-switching power design that preserves efficiency and reduces heat while maintaining full rated output.
• Variable 4-6V hi-level DC offset input turn-on: Simplifies OEM integration by allowing a clean turnout from factory radios without extra wiring.
• High level inputs and MOSFET output stage: Reliable, efficient drive to speakers with solid headroom for dynamic transients.
• 12dB/octave Butterworth crossover: Precise high-pass and low-pass filtering to shape the frequency range for front-stage or bridged configurations.
• 1 Year Warranty and CTA-2006 Compliant: Industry-standard reliability and compatibility benchmarks.
• Number of Channels: 2; Total Power: 300 Watts; Rated Power: 100W x 2 @ 4-Ohm, 150W x 2 @ 2-Ohm, 300W x 1 @ 4-Ohm (bridged)

The PBR300X2 is ideal for a small, high-performance 2-channel front stage or for bridged subwoofer configurations in compact builds. Its non-switching, efficient BRT design minimizes heat and allows a smaller footprint, while 4-Pin hi-level input and DC offset turn-on simplify OEM integration. With bridgeable power up to 387 Watts at 4 Ohms and comprehensive crossover options, it suits tight, high-sPL installations without compromising tonal control.
