alright i am having trouble designing my new system. i have limitied space behind the seat in my pickup and am looking at either a w7 or w6 ported. The site i used to custom build my boxes shut down so now i am having trouble trying to think of the box. the site still works and according to the site the 1.75cuft with a port in it would not work. no i am wondering if it is possible to make a ported subwoofer box that would be 13.5 inches high 14 inches wide and the depth would not matter. is there a site that would give me directions and plans on how to build a ported enclosure.
