2 Rockford Fosgate Punch P1S4-12 12" 500W 4-Ohm Power Car Audio Subwoofers Rockford Fosgate showcases its 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 an impressive sound that'll stand out in a crowd. Engineers at Rockford Fosgate designed the 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 P1S4-12 sub-features an extended pole piece and bumped backplate that leaves more room for a 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.
