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.
Overview

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.

Klippel Verified
Klippel is a speaker certification program allowing us to deliver the best possible subwoofers.
Anodized Aluminum Voice Coil Former
Rockford Fosgate subwoofers use anodized aluminum voice coil formers that provide superior heat dissipation (up to 100° at full power levels). Unlike traditional plastic substitutions, aluminum acts like a heat-sink to quickly dissipate thermal build-up on the voice coil. This keeps subwoofers cool during high SPL conditions.
FlexFit Basket - Subwoofer
The slot mounted frame pattern allows fine-tuning of the subwoofer's mounting position.
