Its dual-coil configuration provides wiring flexibility for matching a compatible mono or multi-channel amplifier. It is suited to listeners building a dedicated bass system or upgrading an existing subwoofer enclosure.\u003c\/p\u003e\u003cp\u003eWith a 600-watt RMS power rating and 1,200-watt maximum rating, this subwoofer is intended for amplified installations rather than direct connection to a factory radio. Its stated frequency response reaches from 28 Hz to 250 Hz for bass-focused playback. The 85 dB sensitivity specification and 12-inch cone make it appropriate for systems designed around solid, sustained low-end output.\u003c\/p\u003e\u003cp\u003eThe P3D4-12 uses an anodized aluminum cone and dustcap with a Santoprene rubber surround. This combination is built to support cone control and durability during high-excursion bass reproduction. A 2.5-inch, four-layer high-temperature voice coil is reinforced with a spun-laced Nomex collar.\u003c\/p\u003e\u003cp\u003eRockford Fosgate incorporates a StampCast hybrid basket, integrated spider venting, and an extended pole piece with a bumped vented backplate. These design elements are intended to support structural rigidity and motor cooling. The VAST surround design increases effective cone area compared with a conventional surround attachment.\u003c\/p\u003e\u003cp\u003eThis subwoofer can be used in sealed or vented enclosures depending on the desired system response and available vehicle space. A sealed box offers a compact installation path, while the recommended vented design is tuned for stronger output around its port tuning frequency. Its dual 4-ohm coils can be wired in series or parallel to create an 8-ohm or 2-ohm nominal load for a compatible amplifier.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e600-Watt RMS Rating:\u003c\/strong\u003e Supports amplifier matching for sustained bass playback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 4-Ohm Voice Coils:\u003c\/strong\u003e Allows 2-ohm or 8-ohm wiring configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnodized Aluminum Cone:\u003c\/strong\u003e Provides a rigid diaphragm for bass reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStampCast Hybrid Basket:\u003c\/strong\u003e Combines strength with reduced resonance and weight.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpider Venting:\u003c\/strong\u003e Helps move air around the motor structure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-AWG Push Terminals:\u003c\/strong\u003e Accommodate substantial speaker wire for secure connections.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe P3D4-12 uses an anodized aluminum cone and dustcap, Santoprene surround, dual linear spiders, and a protective PVC-textured magnet cover. Its high-temperature, four-layer voice coil uses a spun-laced Nomex reinforcement collar, while the basket integrates venting around the spider area. A diamond-cut cast-aluminum trim ring is included, and the design accepts an optional grille.\u003c\/p\u003e\u003cp\u003eAllow for an 11.25-inch cutout and 6.66-inch mounting depth, plus sufficient clearance behind the motor and terminals. Rockford Fosgate specifies a 0.75 to 1.25 cubic-foot sealed enclosure range or a 1.79 cubic-foot optimum vented enclosure; enclosure volume should account for driver and port displacement. Use an amplifier and wiring configuration compatible with the final 2-ohm or 8-ohm nominal load, and use a subsonic filter with a vented enclosure.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45634341273670,"sku":"P3-D4-12","price":259.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61K01-QkdML_ea2f0239-eeb3-40d6-b378-930b5bfda0fb.jpg?v=1784430736","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-p3d4-12-12-dual-4-ohm-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
