Its 3.51-inch mounting depth helps it fit in compact enclosures and space-conscious locations such as suitable under-seat or truck-cab installations. It is intended for car and truck audio upgrades that need substantial bass capability without using a large mounting depth.\u003c\/p\u003e\u003cp\u003eWith a rated 1000 watts RMS power handling and 2000 watts maximum power rating, the STX12SD2 is built for use with a properly matched external subwoofer amplifier. Its 20 Hz to 500 Hz frequency-response specification places its focus on low-frequency reproduction. This makes it a practical choice for adding bass foundation to a full-range vehicle audio system.\u003c\/p\u003e\u003cp\u003eThe subwoofer uses dual 2-ohm voice coils, giving installers flexibility when configuring the final load presented to a compatible amplifier. Voice-coil configuration should be considered alongside the amplifier's stable impedance rating before installation. Careful power matching and correct gain setup are important for using the subwoofer within its RMS rating.\u003c\/p\u003e\u003cp\u003eA die-cast aluminum basket forms the structural foundation of the STX12SD2. This rigid basket design supports the driver assembly while helping maintain a stable mounting platform in a vehicle enclosure. The shallow-format layout is engineered to balance installation flexibility with 12-inch subwoofer fitment.\u003c\/p\u003e\u003cp\u003eThe STX12SD2 has an 11.26-inch cutout diameter and a 12.80-inch overall diameter for enclosure planning. It is suited to custom or replacement enclosures that can accommodate those dimensions and its shallow mounting depth. Pair it with an appropriately designed enclosure, compatible mono or multi-channel amplifier setup, and suitable wiring for a complete bass upgrade.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1000W RMS Handling:\u003c\/strong\u003e Supports amplifier matching based on continuous power capability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2000W Maximum Rating:\u003c\/strong\u003e Provides a published maximum-power reference for system planning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShallow 3.51-Inch Depth:\u003c\/strong\u003e Helps fit installations with limited mounting space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 2-Ohm Voice Coils:\u003c\/strong\u003e Allows flexible wiring with compatible subwoofer amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-Inch Fitment:\u003c\/strong\u003e Uses an 11.26-inch cutout and 12.80-inch outside diameter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDie-Cast Aluminum Basket:\u003c\/strong\u003e Provides a rigid foundation for the subwoofer assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe STX12SD2 uses a die-cast aluminum basket and a shallow-mount driver design. Its compact 3.51-inch mounting depth is the key design consideration for installations where enclosure depth is limited. The 12-inch format retains conventional subwoofer sizing while reducing the space required behind the mounting surface.\u003c\/p\u003e\u003cp\u003eBefore ordering or building an enclosure, verify the 11.26-inch cutout requirement, 12.80-inch overall diameter, and 3.51-inch mounting depth against the available space. Because this is a dual 2-ohm voice-coil subwoofer, the wiring arrangement must match an amplifier that is stable at the resulting impedance. Select an amplifier and enclosure approach appropriate for the subwoofer's 1000-watt RMS power rating, and have installation performed with secure mounting and correctly sized system wiring.\u003c\/p\u003e","brand":"STX Audio","offers":[{"title":"Default Title","offer_id":45663727550534,"sku":"STX12SD2","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61kDVRZ2eTL_b50cde37-9c71-43c0-ab1e-535606014e2c.jpg?v=1784449532","url":"https:\/\/audiowatt.store\/products\/stx-audio-stx12sd2-12-shallow-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
