hey everyone i know this is a dead thread, but i am no longer working on this design, i scrapped the whole project and started fresh from the sub-frame up, if anyone is still interested i have what i think is a much cleaner and functional design that i created for the subwoofer enclosure, sadly enough the entire trunk is not finished but not a priority, one day it will be finished but for now i have a fully functional trunk and sub enclosure to enjoy
