It combines one Punch P1S4-12 single-voice-coil subwoofer with a vented enclosure that is wired for a 4-ohm amplifier load. This makes it a practical option for listeners who want a straightforward bass upgrade from an external amplifier.\u003c\/p\u003e\u003cp\u003eThe ported enclosure is intended to provide strong low-bass output while retaining controlled, musical bass response. With 250 watts RMS and 500 watts maximum power handling, it is suited to systems using a properly matched mono or bridged amplifier stable at 4 ohms. Its 25-250 Hz frequency response covers the bass region typically handled by a dedicated subwoofer.\u003c\/p\u003e\u003cp\u003eInside, the P1S4-12 uses a Kevlar-reinforced paper cone, high-density NBR surround, poly-cotton spider, and high-temperature voice coil. The driver also uses spider venting, an extended pole piece, and a vented backplate to support heat management during normal operation. These construction details support a durable subwoofer foundation in a ready-to-install enclosure.\u003c\/p\u003e\u003cp\u003eThe enclosure uses 5\/8-inch MDF, high-density black carpet, a front-firing high-flow port, and high-current connection hardware. Its port design is made to move air efficiently while helping reduce audible port noise. The angled, compact enclosure format is suitable for trunk or cargo-area installations where a self-contained bass solution is preferred.\u003c\/p\u003e\u003cp\u003eThe P1-1X12 requires a separate amplifier, amplifier wiring, and an audio signal connection appropriate for the vehicle's system. Its internally wired 4-ohm load simplifies amplifier matching because there is one enclosure input connection rather than separate voice-coil wiring. It can serve as a first dedicated subwoofer upgrade or as the bass section of a larger Rockford Fosgate system.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoaded 12-Inch Enclosure:\u003c\/strong\u003e Includes one Punch P1S4-12 subwoofer in a finished vented box.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Ohm Final Load:\u003c\/strong\u003e Internal wiring presents a 4-ohm load to a compatible amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e250-Watt RMS Handling:\u003c\/strong\u003e Supports properly matched external amplification for sustained bass playback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVented Cabinet:\u003c\/strong\u003e The ported design supports efficient low-frequency output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5\/8-Inch MDF Construction:\u003c\/strong\u003e Provides a rigid enclosure structure for the installed woofer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Current Terminals:\u003c\/strong\u003e Compression connections accept speaker wire up to 10 AWG.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe P1-1X12 enclosure is built from 5\/8-inch medium-density fiberboard and finished in high-density black carpet. It houses a single 12-inch Punch P1 driver and uses a proprietary high-flow, low-noise port. The driver incorporates a Kevlar-reinforced paper cone, NBR surround, stamped steel frame, protective PVC motor cover, and a soft-touch trim ring.\u003c\/p\u003e\u003cp\u003eMount the enclosure securely in a trunk, hatch, or cargo area where its 15.125-inch height, 19.125-inch width, and 15.75-inch depth can be accommodated. Connect the amplifier's positive speaker output to the enclosure's red terminal and its negative output to the black terminal, using appropriately sized speaker cable. Use an external amplifier designed to deliver power safely into a 4-ohm load, and disconnect the vehicle battery's negative terminal before installation.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45634052948038,"sku":"P1-1X12","price":289.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71EQwNJq9KL.jpg?v=1784427822","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-p1-1x12-12-ported-loaded-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
