The Best Performing Rockford Fosgate Punch Series Subwoofer


The P3D4-15 is the best performing Rockford Fosgate Punch series subwoofer. The P3 15” features Dual 4-Ohm voice coils, 600 Watts RMS of power handling, and accommodates a grille insert using the included cast aluminum trim ring.

The P3D4-15 is Rockford Fosgate’s best performing Punch series subwoofer. The P3 subwoofers now feature anodized aluminum cones and dustcaps along with unique spider venting to keep the motor cooler than previous versions. These feature VAST technology to increase surface cone area up to 25% and a FlexFit basket for extreme installations. Best of all, a new hybrid stamp-cast basket offers the best of both worlds by providing super strength while minimizing weight and resonance.
