Its 3.51-inch mounting depth helps make it suitable for compact custom enclosures and other space-conscious vehicle installations. The dual 4-ohm voice-coil design provides wiring flexibility when matching the subwoofer to a compatible amplifier.\u003c\/p\u003e\u003cp\u003eRated for 1000 watts RMS and 2000 watts maximum power, the STX12SD4 is intended for car audio systems that need substantial low-frequency output from a shallow driver. Its stated 20Hz to 500Hz frequency-response range covers deep bass frequencies while extending into the upper-bass region. This makes it a practical option for listeners building a dedicated bass section into an upgraded vehicle audio system.\u003c\/p\u003e\u003cp\u003eThe shallow profile addresses a common installation challenge in trucks, compact cars, and low-profile enclosure projects: fitting a full-size 12-inch subwoofer without requiring the depth of a conventional design. An 11.26-inch cutout requirement and 12.80-inch overall diameter should be checked against the planned enclosure before installation. Careful measurement remains important because mounting clearance can vary by vehicle and enclosure construction.\u003c\/p\u003e\u003cp\u003eSTX Audio uses a die-cast aluminum basket for the STX12SD4. This rigid basket construction supports the driver assembly and is intended to help limit unwanted structural vibration. The result is a durable foundation for a subwoofer installed in a properly designed enclosure.\u003c\/p\u003e\u003cp\u003eFor a complete system, the STX12SD4 needs an external amplifier, an appropriate enclosure, and correctly sized wiring. Its dual 4-ohm voice coils allow the installer to select a wiring arrangement that suits the amplifier's supported load. Matching amplifier output to the 1000-watt RMS rating and following amplifier and enclosure guidance are important parts of a reliable installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-Inch Shallow Driver:\u003c\/strong\u003e Delivers bass capability in installations with limited mounting depth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1000W RMS Handling:\u003c\/strong\u003e Supports use with a properly matched external amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2000W Maximum Power:\u003c\/strong\u003e Provides the stated peak power-handling specification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 4-Ohm Voice Coils:\u003c\/strong\u003e Offers flexible wiring choices for compatible amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3.51-Inch Mounting Depth:\u003c\/strong\u003e Helps fit low-profile and compact enclosure designs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDie-Cast Aluminum Basket:\u003c\/strong\u003e Provides a rigid structural platform for the driver.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe STX12SD4 combines a full 12-inch subwoofer format with a shallow-mount layout. Its die-cast aluminum basket is the confirmed structural component, and the driver has a 12.80-inch overall diameter. The design is intended for installations that need a lower-profile subwoofer rather than a deeper conventional driver.\u003c\/p\u003e\u003cp\u003eConfirm the enclosure has at least the required 11.26-inch cutout and sufficient depth for the 3.51-inch mounting specification before purchase. Use an enclosure appropriate for the driver and connect the dual 4-ohm voice coils according to the amplifier's approved impedance range. An amplifier, enclosure, wiring, and installation hardware are separate system requirements unless supplied by the retailer.\u003c\/p\u003e","brand":"STX Audio","offers":[{"title":"Default Title","offer_id":45663793381446,"sku":"STX12SD4","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61kDVRZ2eTL_31e5435e-c243-44eb-b70c-6ab9a3367bd8.jpg?v=1784449568","url":"https:\/\/audiowatt.store\/products\/stx-audio-stx12sd4-12-shallow-mount-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
