P2D2/D4-10

The Rockford Fosgate Punch P2 subwoofers deliver powerful bass reproduction, high power handling, and the proven sound quality of this American car audio brand. The 25 cm (10") models, the P2D2-10 and P2D4-10, feature a power handling capacity of 300 watts RMS and 600 watts peak, as well as a robust construction for powerful, precise low-frequency reproduction.

The heat-resistant 58-mm dual voice coil, combined with the powerful magnet system, ensures reliable performance even under heavy use. VAST™ technology optimizes the effective diaphragm area, while the durable foam surround and sturdy diaphragm construction enable controlled excursion.

Thanks to their two voice coils, these subwoofers offer flexible connection options and are suitable for both sealed and bass-reflex enclosures. This makes them ideal for high-performance car audio systems with deep, dynamic bass.
