Rockford Fosgate P3D4-15 Punch 15" P3 4-Ohm DVC Subwoofer

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.
