Its dual 4-ohm voice-coil design gives installers series or parallel wiring flexibility when matching the subwoofer to an amplifier. This model is intended for use in a properly designed enclosure and vehicle audio system.\u003c\/p\u003e\u003cp\u003eWith 1,200 watts RMS power handling and a 2,400-watt peak rating, the G3-15D4 is suited to higher-power bass systems when paired with an amplifier that is stable at the selected final impedance. Its 30 Hz to 500 Hz published frequency-response range covers low bass through upper-bass frequencies. The 87 dB sensitivity rating provides a useful reference when planning amplifier power and overall system output.\u003c\/p\u003e\u003cp\u003eThe subwoofer uses a competition-grade pressed paper cone paired with a high-roll foam surround. This combination is designed to support cone movement while maintaining a durable interface between the cone and frame. The result is a purpose-built low-frequency driver for custom car-audio installations.\u003c\/p\u003e\u003cp\u003eGravity specifies an advanced air-flow cooling system to help manage heat during extended operation. Thermal management is important in a high-power subwoofer system because excessive heat can affect long-term voice-coil performance. Proper gain setting and clean amplifier power remain essential for reliable operation.\u003c\/p\u003e\u003cp\u003eThe G3-15D4 fits upgrade paths ranging from a single custom bass enclosure to multi-subwoofer systems. Its two 4-ohm voice coils may be wired in parallel for a 2-ohm final load or in series for an 8-ohm final load per subwoofer. Select an enclosure, amplifier, wiring, and electrical support appropriate for the vehicle and intended listening level.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e15-Inch Woofer:\u003c\/strong\u003e Provides substantial cone area for dedicated bass reproduction in a custom vehicle system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1,200W RMS Handling:\u003c\/strong\u003e Supports amplifier matching based on continuous power rather than peak-only ratings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 4-Ohm Voice Coils:\u003c\/strong\u003e Allows 2-ohm parallel or 8-ohm series wiring for one subwoofer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressed Paper Cone:\u003c\/strong\u003e Uses a competition-grade cone material specified for low-frequency playback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Roll Foam Surround:\u003c\/strong\u003e Supports cone travel and is designed for durable use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir-Flow Cooling System:\u003c\/strong\u003e Helps manage heat during extended high-power operation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe G3-15D4 combines a pressed paper cone, high-roll foam surround, large motor structure, and spring-loaded terminals in a purpose-built subwoofer design. Its 15-inch format requires a suitably rigid enclosure and adequate cargo-space planning. Keep the cone and surround clean, and avoid harsh chemicals or excessive moisture during maintenance.\u003c\/p\u003e\u003cp\u003eInstall the subwoofer securely in a sealed, ported, or bandpass enclosure designed for a 15-inch driver, with no air leaks or mounting obstructions. Wire its dual 4-ohm coils in series for 8 ohms or parallel for 2 ohms, and verify that the amplifier is stable at the resulting load. Set amplifier gain conservatively, use an appropriate low-pass filter, and avoid audible distortion or excessive bass boost.\u003c\/p\u003e","brand":"Gravity","offers":[{"title":"Default Title","offer_id":45626447626310,"sku":"G3-15D4","price":180.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/pixelcut-export_2_06fc83c6-da90-4a25-8188-424b40c9eb01.jpg?v=1784374663","url":"https:\/\/audiowatt.store\/products\/gravity-g3-15d4-15-dual-4-ohm-car-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
