Its compact motor and 2.66-inch mounting depth help it fit in space-limited vehicle locations while adding dedicated low-frequency output. Dual 4-ohm voice coils provide useful wiring flexibility when matching an amplifier.\u003c\/p\u003e\u003cp\u003eThis model is intended for listeners building a compact bass system, replacing a factory subwoofer, or adding low end to a vehicle with limited enclosure depth. It is rated for 150 watts RMS and 300 watts maximum power handling. The 38-250 Hz frequency response supports subwoofer duty when used with an appropriate low-pass crossover.\u003c\/p\u003e\u003cp\u003eThe P3SD4-8 uses an anodized aluminum cone and dustcap with an M-Roll Santoprene surround. These materials are paired with a dual linear spider and embedded tinsel leads to support controlled cone movement. Its 82 dB sensitivity and shallow design make it a practical option for compact, amplifier-driven systems.\u003c\/p\u003e\u003cp\u003eRockford Fosgate equips this shallow P3S model with a StampCast basket and integrated spider venting. The venting design is intended to help manage motor temperature during operation. A shallow motor assembly helps maintain the low mounting-depth requirement without changing the subwoofer's 8-inch fitment format.\u003c\/p\u003e\u003cp\u003eThe P3SD4-8 can be used in either sealed or vented enclosures. Rockford Fosgate specifies a 0.25 cubic-foot sealed enclosure or a 0.75 cubic-foot vented enclosure for this driver. Its dual 4-ohm coils can be wired in series or parallel to create an 8-ohm or 2-ohm final load for a compatible amplifier.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShallow-Mount Design:\u003c\/strong\u003e A 2.66-inch mounting depth supports installations with limited clearance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 4-Ohm Voice Coils:\u003c\/strong\u003e Allows 2-ohm or 8-ohm wiring configurations for one subwoofer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e150W RMS Handling:\u003c\/strong\u003e Matches well with an amplifier rated around its continuous power capability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnodized Aluminum Cone:\u003c\/strong\u003e Provides a rigid cone material for bass reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Spider Venting:\u003c\/strong\u003e Helps the motor manage heat during operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealed Or Vented Use:\u003c\/strong\u003e Supports compact sealed or larger vented enclosure designs.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe P3SD4-8 combines an anodized aluminum cone and dustcap, M-Roll Santoprene surround, dual linear spider, aluminum voice-coil former, and hybrid StampCast basket. It includes a diamond-cut cast-aluminum trim ring, while a grille is optional rather than included. The driver uses dual 10 AWG compression-style speaker terminals.\u003c\/p\u003e\u003cp\u003eConfirm a 7.13-inch cutout and at least 2.66 inches of mounting clearance before installation. Use a properly built sealed 0.25 cubic-foot enclosure or vented 0.75 cubic-foot enclosure, and wire both voice coils for an amplifier-stable final impedance. For subwoofer operation, an active low-pass crossover in the 80-100 Hz range is recommended in the owner's manual.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45635202285638,"sku":"P3SD48","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71QpNi7D3OL_bc90fdb3-cb66-4f73-8652-b5e5aa716e2d.jpg?v=1784432141","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-p3sd4-8-8-shallow-dvc-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
