We are offering a new line of boxes that can fit those larger deeper 8\" subs that wont fit in other boxes.  We are talking about JL Audio 8W7s and Sundown SA 8s and More.  By lifting the seat 2.5\" with a custom lift kit from LMI welding, this opens up the under seat area and allows the proper space needed for these types of subs.  This box comes in a dual slot-ported configuration that will absolutely rock in your truck.  Besides being larger than ordinary boxes, our lift kit boxes are built like army tanks.  They are built completely from 3\/4\" MDF and are glued and screwed together, Internally braced and come with high end push style speaker terminals.  Thats what it takes to contain these massive subs and Subthump knows how to deliver.  \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Subthump.com","offers":[{"title":"Dual 8\" Round Standard Size Holes \/ Charcoal Gray","offer_id":43863025549378,"sku":"CRB14-LK2x8FFP","price":395.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round Standard Size Holes \/ Black","offer_id":43863025582146,"sku":"CRB14-LK2x8FFP","price":415.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round Standard Size Holes \/ Light Gray","offer_id":43863025614914,"sku":"CRB14-LK2x8FFP","price":415.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round Standard Size Holes \/ Plush Light Tan","offer_id":43863025647682,"sku":"CRB14-LK2x8FFP","price":420.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two Sundown SA 8 7.375\" \/ Charcoal Gray","offer_id":43863025680450,"sku":"CRB14-LK2x8FFP","price":410.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two Sundown SA 8 7.375\" \/ Black","offer_id":43863025713218,"sku":"CRB14-LK2x8FFP","price":430.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two Sundown SA 8 7.375\" \/ Light Gray","offer_id":43863025745986,"sku":"CRB14-LK2x8FFP","price":430.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two Sundown SA 8 7.375\" \/ Plush Light Tan","offer_id":43863025778754,"sku":"CRB14-LK2x8FFP","price":435.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two JL 8W7  7\" \/ Charcoal Gray","offer_id":43863025811522,"sku":"CRB14-LK2x8FFP","price":410.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two JL 8W7  7\" \/ Black","offer_id":43863025844290,"sku":"CRB14-LK2x8FFP","price":430.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two JL 8W7  7\" \/ Light Gray","offer_id":43863025877058,"sku":"CRB14-LK2x8FFP","price":430.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two JL 8W7  7\" \/ Plush Light Tan","offer_id":43863025909826,"sku":"CRB14-LK2x8FFP","price":435.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two Skar ZVX8 7.5\" \/ Charcoal Gray","offer_id":43863025942594,"sku":"CRB14-LK2x8FFP","price":410.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two Skar ZVX8 7.5\" \/ Black","offer_id":43863025975362,"sku":"CRB14-LK2x8FFP","price":430.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two Skar ZVX8 7.5\" \/ Light Gray","offer_id":43863026008130,"sku":"CRB14-LK2x8FFP","price":430.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two Skar ZVX8 7.5\" \/ Plush Light Tan","offer_id":43863026040898,"sku":"CRB14-LK2x8FFP","price":435.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two Sundwon X8 7.36\" \/ Charcoal Gray","offer_id":43863026073666,"sku":"CRB14-LK2x8FFP","price":410.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two Sundwon X8 7.36\" \/ Black","offer_id":43863026106434,"sku":"CRB14-LK2x8FFP","price":430.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two Sundwon X8 7.36\" \/ Light Gray","offer_id":43863026139202,"sku":"CRB14-LK2x8FFP","price":430.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8\" Round, Specific for Two Sundwon X8 7.36\" \/ Plush Light Tan","offer_id":43863026171970,"sku":"CRB14-LK2x8FFP","price":435.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8 inch Square \/ Charcoal Gray","offer_id":43863026204738,"sku":"CRB14-LK2x8FFP","price":410.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8 inch Square \/ Black","offer_id":43863026237506,"sku":"CRB14-LK2x8FFP","price":430.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8 inch Square \/ Light Gray","offer_id":43863026270274,"sku":"CRB14-LK2x8FFP","price":430.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8 inch Square \/ Plush Light Tan","offer_id":43863026303042,"sku":"CRB14-LK2x8FFP","price":435.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0667\/9271\/8402\/files\/crb14-lk2x8ffp1sm.jpg?v=1781627220","url":"https:\/\/subthump.com\/products\/2014-2018-gm-crew-cab-dual-8-ported-front-fire-box-lift-kit-reqand-39d-new","provider":"Subthump.com","version":"1.0","type":"link"}
