Rockford Fosgate's P1-1X12 ported enclosure fills your ride with juicy, high-volume bass, so you and your passengers can rock out to the latest beats. The enclosure's Punch P1 12" woofer features a paper cone reinforced with Kevlar fibers, supported by a rubber surround. The heavy-duty motor assembly and advanced cooling vents allow this sub to handle up to 250 watts RMS without flinching. Rugged 5/8" medium-density fiberboard construction means this enclosure will hold strong for fat, heavy bass. Industrial-grade black carpet provides a clean, finished look, and protects your trunk from nicks and scratches. This enclosure uses an advanced port design that promotes generous air movement, while reducing distortion-causing port noise, so you hear louder, deeper bass. Add an amp and some wiring, and feel the thick low end this enclosure adds to your ride.
