Its single 2-ohm voice coil makes it a straightforward choice for an amplifier rated to operate at a 2-ohm load. With 250 watts RMS power handling, it suits systems built for controlled bass reinforcement rather than excessive amplifier power.\u003c\/p\u003e\u003cp\u003eThis subwoofer is intended for listeners who want the added low-end presence of a 15-inch driver while working within a moderate power range. The large cone area helps it move substantial air, supporting bass that can fill larger vehicle cabins. It can be used in either a sealed or ported enclosure, allowing the installation to be tailored to available space and listening preferences.\u003c\/p\u003e\u003cp\u003eThe P1S2-15 uses a Kevlar-paper composite cone, Kevlar dustcap, foam surround, and steel basket. Its 50 mm voice coil is built on an aluminum former, while the single-spider suspension supports stable cone movement. The driver is rated for ±9 mm of linear excursion and a maximum mechanical excursion of ±27 mm.\u003c\/p\u003e\u003cp\u003eFor enclosure planning, Rockford Fosgate specifies a 44.7-liter sealed enclosure or a 75.3-liter ported enclosure. The recommended ported alignment uses a 100 mm diameter port with 80 cm² of port area, a 20 cm port length, and a 34 Hz tuning frequency. These published alignments give installers a practical starting point for building an enclosure around the driver.\u003c\/p\u003e\u003cp\u003eThe P1S2-15 works well as the bass foundation in a system with full-range door speakers and a dedicated mono or subwoofer amplifier. Its 2-ohm single voice coil should be paired with an amplifier that is stable at 2 ohms and appropriately configured for its 250-watt RMS rating. Allow for its 177 mm mounting depth and 353 mm mounting cutout when selecting or building an enclosure.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e15-Inch Subwoofer:\u003c\/strong\u003e Large cone area supports strong low-frequency output in car-audio installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm SVC Design:\u003c\/strong\u003e A single 2-ohm voice coil simplifies amplifier and wiring selection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e250 Watts RMS:\u003c\/strong\u003e Continuous power rating supports proper amplifier matching and system setup.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKevlar-Paper Composite Cone:\u003c\/strong\u003e Composite cone construction provides a rigid diaphragm for bass reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e50 mm Voice Coil:\u003c\/strong\u003e High-temperature voice coil uses an aluminum former for thermal durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealed Or Ported Compatibility:\u003c\/strong\u003e Published enclosure recommendations support different installation goals.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe P1S2-15 is constructed around a steel basket with a Kevlar-paper composite cone, Kevlar dustcap, and foam surround. A single spider with embedded tinsel leads supports the moving assembly, while the aluminum voice-coil former and 50 mm coil are designed for the driver’s rated power range. Custom 10-AWG nickel-plated push terminals provide the speaker-wire connection point.\u003c\/p\u003e\u003cp\u003eInstall the subwoofer in an enclosure with at least a 353 mm mounting cutout and 177 mm of mounting-depth clearance. For a sealed build, use the specified 44.7-liter enclosure volume; for a ported build, use the 75.3-liter recommendation with the published port dimensions and 34 Hz tuning. Pair it with a 2-ohm-stable subwoofer amplifier and set gain carefully to remain within the 250-watt RMS rating.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45634158723142,"sku":"P1S2-15","price":189.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61_bzqvHtqL.jpg?v=1784428279","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-p1s2-15-15-2-ohm-svc-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
