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.
