Product details
All-in-one Punch powered bass
P300-12 is Rockford’s Punch 12-inch powered sealed enclosure for installs that want bass without a separate amplifier. A proprietary high-output 12-inch woofer is matched to a built-in 300 W RMS Class-D amplifier in a closed-loop design. Frequency response is 35 Hz to 200 Hz. Power and ground use 8 AWG with a detachable power/ground connector. An extruded aluminum heat sink and thermal / over-under voltage protection keep the amp in check.

On-board controls cover a variable 50–200 Hz 12 dB/octave Butterworth low-pass crossover, adjustable bass boost, and a 0° / 180° phase switch.
