ROCKFORD FOSGATE P1S4-12

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%.
