Its dual 4-ohm voice coil configuration provides wiring flexibility for matching a compatible mono or multi-channel amplifier. It is intended for listeners building or upgrading a system that needs stronger bass than typical full-range vehicle speakers can provide.\u003c\/p\u003e\u003cp\u003eWith a 600-watt RMS and 1,200-watt peak power rating, the GR-12PW is suited to amplification selected around its continuous power capability. Its stated 30 Hz to 2.5 kHz frequency response supports low-bass reproduction while allowing an external amplifier or processor to set the appropriate low-pass crossover. The 90 dB sensitivity rating indicates efficient output relative to input power.\u003c\/p\u003e\u003cp\u003eThe subwoofer uses a competition-grade pressed paper cone intended to keep the moving assembly responsive for bass playback. A high-roll foam surround supports cone travel while helping the driver reproduce lower frequencies. Together, these materials are designed for the demands of a dedicated automotive subwoofer installation.\u003c\/p\u003e\u003cp\u003eGravity specifies an advanced airflow cooling system to help manage heat during sustained use. Heat control is especially important when a subwoofer is driven near its rated continuous-power range. Proper gain setting and a clean amplifier signal remain important for reliable operation.\u003c\/p\u003e\u003cp\u003eThe GR-12PW can be used as the bass section of a custom car audio system with an external amplifier, enclosure, wiring, and source signal. Its two 4-ohm voice coils can be wired in parallel for a 2-ohm nominal load or in series for an 8-ohm nominal load. Choose the enclosure, amplifier, and wiring arrangement according to the amplifier manufacturer's supported impedance and power ratings.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-Inch Subwoofer:\u003c\/strong\u003e Adds dedicated bass capability to an aftermarket vehicle audio system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 4-Ohm Voice Coils:\u003c\/strong\u003e Supports series or parallel wiring options for compatible amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e600W RMS Rating:\u003c\/strong\u003e Provides a continuous-power reference for amplifier matching.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressed Paper Cone:\u003c\/strong\u003e Uses a lightweight cone material for responsive bass reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Roll Foam Surround:\u003c\/strong\u003e Supports cone movement during low-frequency playback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow Cooling System:\u003c\/strong\u003e Helps manage heat during extended operation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe GR-12PW combines a competition-grade pressed paper cone with a high-roll foam surround and an advanced airflow cooling system. This construction focuses on the moving parts and thermal management needed for a dedicated bass driver. The driver is a passive, wired subwoofer and requires external amplification.\u003c\/p\u003e\u003cp\u003eInstall the GR-12PW in a properly sized enclosure and use an amplifier that is stable at the final impedance created by the voice-coil wiring. Wire its coils in parallel only when the amplifier supports a 2-ohm load; series wiring produces an 8-ohm nominal load. Set amplifier gain carefully, use an appropriate low-pass crossover, and verify mounting clearance before choosing an enclosure.\u003c\/p\u003e","brand":"Gravity","offers":[{"title":"Default Title","offer_id":45627159707718,"sku":"GR-12PW","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/714J0GXmghL.jpg?v=1784375200","url":"https:\/\/audiowatt.store\/products\/gravity-gr-12pw-12-dual-4-ohm-car-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
