  • Kevlar fiber-reinforced paper cone: Combines strength with the responsive performance needed for hard-hitting bass.
  • VAST technology: Increases the woofer cone’s effective radiating area by up to 25%.
  • Durable StampCast basket: Features integrated spider venting, an extended pole piece, and a bumped vented backplate.
  • Linear spider: Includes embedded 16-AWG tinsel leads for a rugged suspension design.
  • Flexible enclosure options: Performs best in standard sealed and vented enclosures.
  • Protective finishing details: Includes a soft-touch rubberized ABS trim ring that accommodates an optional grille, plus a textured PVC magnet cover.

The Rockford Fosgate P1S4-12 brings the Punch family’s signature bass presence to cars and trucks. Its 12-inch cone moves the low notes with the depth and weight that make bass lines roll through the cabin, while kick drums land with a firm, satisfying impact. Whether installed in a sealed or vented enclosure, this subwoofer is built to add the rumble and low-frequency force that let you feel the music as much as hear it.
