Product Description

Features & Specifications



Rockford Fosgate P1S4-12 Punch 12″ P1 4-Ohm SVC Subwoofer

Rockford Fosgate P1S4-12 12” is the first in a family of famous “Punch” subwoofers for cars and trucks. The P1S4-12 features a 4-Ohm voice coil, 250 Watts RMS power handling, and can accommodate a grille insert using the included soft touch ABS trim ring. 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.

Rockford Fosgate showcases their fanatical commitment to sonic excellence in the Punch Series of speakers, amps, and subs. If you like to listen to potent, powerful music — and feel it too — Punch components will give you impressive sound that’ll stand out in a crowd.

Engineers designed the Rockford Fosgate P1S4-12 12″ subwoofer to dish out the kind of powerful low end you crave in your ride. Its responsive paper cone is reinforced with the same Kevlar fibers used in bulletproof vests so you get the best of both worlds — warm bass that’s exceptionally hard-hitting. Rockford Fosgate uses a new technique to attach the oversized rubber surround to the cone that increases available cone area up to 25%, so this sub can push more air for even bigger bass.

The Rockford Fosgate P1S4-12 sub features an extended pole piece and bumped backplate that leaves more room for heavy excursion, so it’ll hit deeper lows without “bottoming out.” This sub works equally well in a sealed or ported enclosure, so you can choose the kind of bass you want for your system.
