It adds low-frequency support without requiring a conventional trunk-mounted subwoofer enclosure. Its shallow, round form factor is intended for drivers who want to preserve usable cargo space.\u003c\/p\u003e\u003cp\u003eThis all-in-one system combines a 12-inch subwoofer, sealed enclosure, and integrated amplifier in one assembly. The amplifier is rated at 150 watts RMS and 600 watts maximum, with a 2-ohm final impedance. It is suited to filling in bass response for factory or aftermarket car-audio systems.\u003c\/p\u003e\u003cp\u003eThe VPSTX12 is specified for a 20 Hz to 150 Hz frequency response and includes an adjustable 50 Hz to 150 Hz low-pass filter. A variable bass boost and selectable phase setting help tailor its low-frequency output to the vehicle and system. A fixed 20 Hz subsonic filter is also included.\u003c\/p\u003e\u003cp\u003eLow-level RCA and speaker-level input options allow the subwoofer to connect with different head-unit configurations. When speaker-level input is used, the unit has an automatic turn-on circuit if a switched 12-volt turn-on lead is unavailable. A wired remote bass knob is included for convenient level adjustment from the cabin.\u003c\/p\u003e\u003cp\u003eThe shallow spare-tire application is designed around a 14.2-inch outside diameter and 4.7-inch overall height. It can be mounted in spare tires oriented deep-side down, while some deep-side-up spare tires may need to be flipped over first. The supplied 8 mm and 10 mm mounting bolts support installation in many vehicle spare-tire wells.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpare-Tire-Well Design:\u003c\/strong\u003e Uses the spare-tire area to help retain trunk and cargo space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Amplifier:\u003c\/strong\u003e Combines the amplifier and subwoofer in one compact powered assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e150W RMS Output:\u003c\/strong\u003e Provides a continuous-power rating suitable for bass reinforcement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Inputs:\u003c\/strong\u003e Supports RCA low-level and speaker-level source connections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Low-Pass Filter:\u003c\/strong\u003e Lets you set the upper bass cutoff from 50 Hz to 150 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWired Bass Knob:\u003c\/strong\u003e Provides in-cabin adjustment of subwoofer level.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe VPSTX12 uses a shallow sealed spare-tire enclosure with a cast-aluminum exterior and integrated heatsink. Its 12-inch driver uses a polypropylene cone, rubber surround, and ferrite magnet motor structure. The enclosure measures 14.2 inches by 14.2 inches by 4.7 inches, with a 12.6-inch mounting diameter.\u003c\/p\u003e\u003cp\u003eConfirm spare-tire-well clearance, mounting-bolt fitment, and tire orientation before purchase. The unit accepts RCA low-level or speaker-level input, but the manufacturer instructs users not to connect both input types at the same time. A high-quality power kit is required separately; the manual specifies 8 AWG battery power wire and cautions against using CCA wiring kits.\u003c\/p\u003e","brand":"Cerwin Vega","offers":[{"title":"Default Title","offer_id":45619897204806,"sku":"CER-VPSTX12","price":631.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61LwjMgjHEL.jpg?v=1784370704","url":"https:\/\/audiowatt.store\/products\/cerwin-vega-vpstx12-12-powered-spare-tire-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
