{"product_id":"12-ported-powered-subwoofer-enclosure","title":"12\" Ported Powered Subwoofer Enclosure","description":"The JBL GT-BassPro12 is a ported powered subwoofer enclosure designed to add significant bass impact to your vehicle's audio system. It houses a 12\" subwoofer with a polypropylene cone and hi-roll rubber surround, driven by an integrated 150-watt RMS amplifier (450 watts peak power).\n\nJBL engineered this system for the car environment, tuning it for responsive low-frequency output. The enclosure utilizes a unique Slipstream port, which allows for a shorter port length and a wide-mouth opening. This design minimizes port noise and distortion, enabling a more compact enclosure while maintaining high performance. The robust medium-density fiberboard construction ensures durability, complemented by a carpet covering and a protective metal grille.\n\nKey specifications include a variable low-pass crossover ranging from 40-200 Hz at 12 dB\/octave, a frequency response of 35-120 Hz, and a 25A fuse rating. The unit measures 22-1\/2\"W x 14-5\/8\"H x 12\"D1 x 9-1\/8\"D2. An amp wiring kit is recommended for power, and a remote bass-level control is included for convenient adjustment.\n\nEvery order includes 60-day returns, 60-day price-drop protection, and free lifetime tech support.","brand":"JBL","offers":[{"title":"Default Title","offer_id":52688941580600,"sku":"GT-BASSPRO12","price":637.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664720988.png?v=1784898924","url":"https:\/\/store.motormia.co\/products\/12-ported-powered-subwoofer-enclosure","provider":"MOTORMIA","version":"1.0","type":"link"}
