It is a bare subwoofer driver, intended for installation in a compatible enclosure and connection to an external amplifier. Its dual 2-ohm voice coils give system builders wiring flexibility when matching the subwoofer to a suitable mono amplifier.\u003c\/p\u003e\u003cp\u003eThis model is intended for listeners who want substantial bass extension from a large-diameter subwoofer. Its published frequency response of 30 Hz to 500 Hz places it in the range typically handled by a subwoofer rather than full-range speakers. A properly adjusted low-pass crossover helps it blend with the vehicle's main speakers.\u003c\/p\u003e\u003cp\u003eThe G7-15D2 is rated at 2,400 watts RMS and 4,800 watts peak power. These ratings make amplifier selection, gain setup, wiring, and enclosure construction especially important. Use an amplifier that is stable at the final impedance created by the chosen voice-coil wiring.\u003c\/p\u003e\u003cp\u003eA competition-grade pressed paper cone forms the radiating surface, while a high-roll foam surround supports cone movement. The subwoofer also uses an advanced airflow cooling system intended to help manage heat during operation. Together, these construction elements support use in high-output car audio installations.\u003c\/p\u003e\u003cp\u003eBecause it is a single 15-inch driver rather than a loaded enclosure, the G7-15D2 can be used in a custom sealed or ported box selected for the available vehicle space and desired bass character. The two 2-ohm voice coils can be wired in parallel for a 1-ohm final load or in series for a 4-ohm final load. Professional installation is recommended for enclosure, wiring, and amplifier setup.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e15-Inch Driver:\u003c\/strong\u003e Large cone area supports dedicated low-frequency reproduction in a car audio system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2,400W RMS Rating:\u003c\/strong\u003e Supports high-power system designs when paired with an appropriately matched amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 2-Ohm Voice Coils:\u003c\/strong\u003e Allows series or parallel wiring to suit compatible amplifier loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressed Paper Cone:\u003c\/strong\u003e Competition-grade cone material provides the driver’s primary sound-producing surface.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Roll Foam Surround:\u003c\/strong\u003e Supports cone travel while forming the outer edge of the moving assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow Cooling System:\u003c\/strong\u003e Designed to aid heat management during sustained high-output operation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe G7-15D2 uses a competition-grade pressed paper cone and high-roll foam surround in a 15-inch subwoofer format. Its dual voice-coil layout provides two 2-ohm coils, and the published design also incorporates advanced airflow cooling. The product is supplied as one standalone subwoofer driver rather than a preloaded enclosure.\u003c\/p\u003e\u003cp\u003eInstall the subwoofer in a properly built, sealed enclosure with no air leaks, using mounting hardware appropriate for the enclosure material. Wire both voice coils with correct polarity: parallel wiring creates a 1-ohm final load, while series wiring creates a 4-ohm final load. Confirm that the amplifier is stable at the chosen load, use a low-pass filter, and set amplifier gain carefully to prevent clipping.\u003c\/p\u003e","brand":"Gravity","offers":[{"title":"Default Title","offer_id":45626620510278,"sku":"G7-15D2","price":642.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/91vCWdMd1mL.jpg?v=1784374884","url":"https:\/\/audiowatt.store\/products\/gravity-g7-15d2-15-dual-2-ohm-car-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
