i have all my stuff now, and was going to get boxes built. but now seems like good time to learn a bit about ported boxes so im going to build. i have table saw, circular and new jig saw. i have couple questions as far as the ports. im building 2 seperate boxes that will be in a wall in honda civic coupe. the dimensions of each box will be 18" wide x 30" tall x 20" D, can be 22" deep if needed. the book with subs calls for 3.5 x 16.25 port 13.73" long. what will the tuning be on this and do those dimensions seem like enough air space? they call for 6 cubes and that includes sub displacement but need to add port displacement and im not sure about that. each sub will be wired to 1 ohm with about 1300 watts. thanks for help
