Well i guess my only options are to get 1 separate ported boxes for each side and have my rear seat folded up? 2 boxes that are 1.75cu ft and 34hz for each sub right? Or would one large dual 12" box be better? I don't want to try and sell these subs and sealed box. Then have to buy or make another box because i haven't used these very much yet and won't get much MULA back for them. They do sound much much better now thanks to all your suggestions! Thank you! I would love to have 2 good 10s forward firing but don't wan't to spend another 4-500 on subs and box. I know, I'm probably being a frugal bastard in the sense of quality spl stuff.
