Ok so i called DD today to get some info on their DD1508. The pricing isnt too bad but they said it was not designed to work in a sealed enclosure. Looks like i need to keep looking.Any more suggestions guys? Maybe some 10s that could fit in this box?? im not familiar with fiberglass or id attempt to make my own box to give me some more space. Hell i may end up doing it anyway and lift the seat a few inches.... Thoughts?
