It is intended for listeners who want deeper bass than full-range door or rear-deck speakers can provide. Its dual 4-ohm voice-coil design gives system builders wiring flexibility when matching a compatible amplifier.\u003c\/p\u003e\u003cp\u003eWith a published 1,500-watt RMS power rating and 3,000-watt peak power rating, the GW12D4 is built for high-power bass applications. The 30 Hz to 500 Hz frequency-response specification focuses its role on the lower portion of the audio spectrum. An 85 dB sensitivity rating is published for this model.\u003c\/p\u003e\u003cp\u003eThe subwoofer uses a competition-grade pressed paper cone to produce bass output while maintaining a purpose-built mobile-audio design. Its high-roll foam surround supports cone movement and is intended to provide a durable interface between the cone and frame. These materials are paired for systems where bass impact and controlled low-frequency reproduction are priorities.\u003c\/p\u003e\u003cp\u003eGravity specifies an advanced airflow cooling system for the GW12D4. This design is intended to help manage heat during extended playback at higher power levels. Proper gain setting and amplifier matching remain important for helping the subwoofer operate within its published power-handling range.\u003c\/p\u003e\u003cp\u003eThe GW12D4 can be used in a custom enclosure as part of a bass-focused vehicle upgrade. Its dual 4-ohm voice coils can be wired to suit an amplifier that supports the resulting load. Select an enclosure, amplifier, wiring, and protection hardware appropriate for the vehicle and the final system impedance.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-Inch Subwoofer:\u003c\/strong\u003e Provides dedicated low-frequency reinforcement for car audio systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1,500W RMS Rating:\u003c\/strong\u003e Supports high-power amplifier matching when correctly configured.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 4-Ohm Voice Coils:\u003c\/strong\u003e Offers series or parallel wiring flexibility for compatible amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressed Paper Cone:\u003c\/strong\u003e Uses a competition-grade cone material for bass reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Roll Foam Surround:\u003c\/strong\u003e Supports cone travel while contributing to durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow Cooling System:\u003c\/strong\u003e Helps manage heat during sustained high-output listening.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe GW12D4 combines a competition-grade pressed paper cone with a high-roll foam surround and an advanced airflow cooling system. Its design is focused on car-audio bass duty rather than full-range playback. The published response range of 30 Hz to 500 Hz reflects its intended low-frequency role.\u003c\/p\u003e\u003cp\u003eInstall the subwoofer in an enclosure designed for a 12-inch driver and securely mount it according to the enclosure manufacturer's instructions. Because it has dual 4-ohm voice coils, confirm the final wired impedance before connecting an amplifier; the coils can produce a 2-ohm parallel load or an 8-ohm series load. Use an amplifier whose RMS output and stable impedance range are appropriate for the completed system, and set gains carefully.\u003c\/p\u003e","brand":"Gravity","offers":[{"title":"Default Title","offer_id":45629664133190,"sku":"GW12D4","price":257.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/1_e4b5ad5d-1b46-414d-a49b-10b3499229af.jpg?v=1784376730","url":"https:\/\/audiowatt.store\/products\/gravity-gw12d4-12-dual-4-ohm-car-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
