Its 4-way design combines multiple drivers in each speaker to cover bass, midrange, and high-frequency content from one mounting position. This makes it a practical choice for refreshing worn factory speakers without changing the basic layout of a vehicle audio system.\u003c\/p\u003e\u003cp\u003eWith a 4-ohm impedance, the SGR404 is intended for use with common car-stereo speaker outputs and compatible aftermarket amplification. The stated 85 dB sensitivity and 70 Hz to 20 kHz frequency response describe a compact speaker focused on broad everyday music playback. As with any 4-inch speaker, installation location and available mounting depth should be checked before purchase.\u003c\/p\u003e\u003cp\u003eThe woofer uses a silver alpha cellulose cone paired with a moisture-resistant rubber surround. This material combination is intended to support regular in-vehicle use, where speakers may be exposed to heat, vibration, and changing humidity. A neo mylar soft-dome tweeter is included as part of the coaxial driver assembly.\u003c\/p\u003e\u003cp\u003eGravity equips the SGR404 with an anti-resonant stamped-steel basket to provide a stable mounting structure. Spade speaker terminals simplify connection to conventional speaker wiring. The speaker pair has a stated maximum power handling of 200 watts.\u003c\/p\u003e\u003cp\u003eThe SGR404 can be used in an entry-level system upgrade, a factory-speaker replacement project, or a compact multi-speaker installation. It is supplied as a pair, allowing replacement of two matching speaker positions at once. Speaker wire and mounting screws are included for installation support.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Inch Coaxial Format\u003c\/strong\u003e Fits compact speaker locations where a 4-inch replacement is required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Way Driver Design\u003c\/strong\u003e Combines multiple driver elements for broad frequency coverage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Ohm Impedance\u003c\/strong\u003e Supports connection with many standard car audio speaker outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSilver Alpha Cellulose Cone\u003c\/strong\u003e Provides the primary cone material for the woofer section.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMoisture-Resistant Rubber Surround\u003c\/strong\u003e Helps support durability in an automotive environment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStamped-Steel Basket\u003c\/strong\u003e Provides a rigid speaker frame for mounting stability.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe SGR404 uses silver alpha cellulose cones, moisture-resistant rubber surrounds, neo mylar soft-dome tweeters, and stamped-steel baskets.

Connect each speaker with correct polarity and use the included mounting screws where suitable for the vehicle mounting surface. The included speaker wire may assist with basic wiring, though vehicle-specific adapters or mounting hardware may still be needed.\u003c\/p\u003e","brand":"Gravity","offers":[{"title":"Default Title","offer_id":45631200100422,"sku":"SGR404","price":28.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/81dZhEIdAvL.jpg?v=1784377658","url":"https:\/\/audiowatt.store\/products\/gravity-sgr404-4-4-way-coaxial-car-speakers","provider":"Audio Watt Store","version":"1.0","type":"link"}
