The box fits great and sounds even better.  It molds around \nevery part of the under seat area, including all the tricky seat bracing and \nsupports for an authentic-custom look.  You don't even have to take out the \njack.  One of our customers suggested that you can drill another hole in \nthe bass plate of the jack so it can simply be rotated out of the way and \nre-positioned.  Other than that, just drop the box into place and start. \nthumpin'.  \u003c\/span\u003e\u003c\/p\u003e\n\u003cp align=\"left\"\u003e\u003cspan style=\"FONT-SIZE: small\"\u003eThis is a two-chamber \u003cspan style=\"TEXT-DECORATION: underline\"\u003esealed\u003c\/span\u003e box with .55 cu.ft. of air \nspace per chamber. It is meant for two 10s or two 8s only.  There is no way \nto fit 12s in this box so please do not ask.  Two 10s were a challenge and \npound quite nicely.  Standard mounting depth is now 6-1\/8\", and is even \nexpandable to 6-5\/8\" if you add a 1\/2 spacer.  There is no other crew cab \nbox anywhere with a mounting depth that deep.  There are a few knock-off \nimitations out there but don't fall prey to their \ngimmicks.  \u003c\/span\u003e\u003c\/p\u003e\n\u003cp align=\"left\"\u003e\u003cspan style=\"FONT-SIZE: small\"\u003eThis box is a must-have if you like \nyour bass low and loud in your HD crew cab.  With out a doubt, this is the \nloudest best sounding style box you can put in your crew cab, making this box \nour best selling box for this truck.  Don't settle for anything less than a \nquality  crew cab box from Subthump.  If some other imitation looks \n'cheap', it probably is just that.  Our box is the real deal.  Get \nyours today, they are going faster than ever!\u003c\/span\u003e \u003c\/p\u003e\n\u003cp align=\"left\"\u003e \u003c\/p\u003e","brand":"Subthump.com","offers":[{"title":"Dual 10 inch Round \/ Charcoal Gray","offer_id":43862991241282,"sku":"CHD-210","price":139.0,"currency_code":"USD","in_stock":true},{"title":"Dual 10 inch Round \/ Light Gray","offer_id":43862991274050,"sku":"CHD-210","price":159.0,"currency_code":"USD","in_stock":true},{"title":"Dual 10 inch Round \/ Black","offer_id":43862991306818,"sku":"CHD-210","price":159.0,"currency_code":"USD","in_stock":true},{"title":"Dual 10 inch Round \/ Plush Light Tan","offer_id":43862991339586,"sku":"CHD-210","price":164.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8 inch Round \/ Charcoal Gray","offer_id":43862991372354,"sku":"CHD-210","price":154.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8 inch Round \/ Light Gray","offer_id":43862991405122,"sku":"CHD-210","price":174.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8 inch Round \/ Black","offer_id":43862991437890,"sku":"CHD-210","price":174.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8 inch Round \/ Plush Light Tan","offer_id":43862991470658,"sku":"CHD-210","price":179.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8 inch Square \/ Charcoal Gray","offer_id":43862991503426,"sku":"CHD-210","price":154.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8 inch Square \/ Light Gray","offer_id":43862991536194,"sku":"CHD-210","price":174.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8 inch Square \/ Black","offer_id":43862991568962,"sku":"CHD-210","price":174.0,"currency_code":"USD","in_stock":true},{"title":"Dual 8 inch Square \/ Plush Light Tan","offer_id":43862991601730,"sku":"CHD-210","price":179.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0667\/9271\/8402\/files\/crew3sm.jpg?v=1781627079","url":"https:\/\/subthump.com\/products\/01-06-gm-hd-crew-cab-dual-downfire-box-best-seller","provider":"Subthump.com","version":"1.0","type":"link"}
