Rockford Fosgate P1 12" are the first in a family of world famous subwoofers called "The Punch". During their inception in the 1980's, they quickly became "The Woofer of Choice" for fanatic car audio systems, with a continued tradition today. Kevlar fiber reinforced paper cones deliver bass impact you can feel, and our VAST technology in the Punch P1 woofer increases woofer surface cone area by up to 25%. Best in standard sealed and vented enclosures. Includes soft touch ABS trim ring.

Klippel Verified

Klippel is a speaker certification program allowing us to deliver the best possible subwoofers.

FlexFit Basket

The slot mounted frame pattern allows fine-tuning of the subwoofer's mounting position.

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.

Stitched Tinsel Leads

Improved reliability and performance by reducing fatigue and possible shorting.
