It is intended for listeners building or upgrading a system that needs dedicated bass reproduction beyond what full-range door speakers typically provide. Its dual 4-ohm voice coil design gives installers wiring flexibility when matching the subwoofer to a compatible amplifier.\u003c\/p\u003e\u003cp\u003eRated for 600 watts RMS and 1,200 watts peak power handling, the GW-8D4 is suited to systems built around a properly matched external subwoofer amplifier. The published frequency response of 30 Hz to 500 Hz supports its role as a bass driver. Use an amplifier crossover to limit higher-frequency content and integrate the subwoofer with the rest of the speaker system.\u003c\/p\u003e\u003cp\u003eThe subwoofer uses a competition-grade pressed paper cone and a high-roll foam surround. This combination is specified to support cone movement while maintaining the structure needed for bass playback. The design is focused on a direct, dedicated subwoofer installation rather than a full-range speaker application.\u003c\/p\u003e\u003cp\u003eGravity specifies an advanced airflow cooling design and a high-flux motor arrangement for the GW-8D4. These features are intended to help manage heat during sustained operation. As with any high-power subwoofer, clean amplifier power and appropriate gain setup are important for reliable use.\u003c\/p\u003e\u003cp\u003eThe compact 8-inch format can work well in installations where enclosure space is limited or where multiple smaller drivers are preferred. The GW-8D4 is supplied as a single bare subwoofer, allowing the enclosure and amplifier to be selected separately. Confirm enclosure fitment, mounting dimensions, and final system impedance before installation because those details were not published in the available product specifications.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e8-Inch Subwoofer:\u003c\/strong\u003e Adds dedicated bass output in a compact driver format.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e600 Watts RMS:\u003c\/strong\u003e Supports continuous power handling with a suitably matched amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1,200-Watt Peak Rating:\u003c\/strong\u003e Provides the published maximum peak power-handling specification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 4-Ohm Voice Coils:\u003c\/strong\u003e Offers wiring flexibility for compatible amplifier configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressed Paper Cone:\u003c\/strong\u003e Provides the specified competition-grade cone construction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow Cooling Design:\u003c\/strong\u003e Helps manage heat during extended high-output operation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe GW-8D4 combines a pressed paper cone with a high-roll foam surround, dual voice coils, and a high-flux motor design. Its published construction is intended for car-audio bass duty, with an airflow cooling system integrated to support thermal management. The subwoofer is sold as a single driver rather than as a preloaded enclosure.\u003c\/p\u003e\u003cp\u003eInstall the GW-8D4 in an enclosure designed for an 8-inch subwoofer after confirming its required cutout, mounting depth, and enclosure-volume requirements with the enclosure manufacturer or installer. Wire its dual 4-ohm voice coils only in a configuration supported by the connected amplifier, and set amplifier gain and low-pass filtering correctly. A compatible external amplifier, enclosure, wiring, and installation hardware are required for operation and are not confirmed as included.\u003c\/p\u003e","brand":"Gravity","offers":[{"title":"Default Title","offer_id":45629998858310,"sku":"GW8D4","price":172.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/1_fad733af-4534-4b8f-9536-3f1cd2079bc0.jpg?v=1784376902","url":"https:\/\/audiowatt.store\/products\/gravity-gw-8d4-8-inch-dual-4-ohm-car-audio-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
