well, i am glad it worked out for you. But I'm still upset. I was hoping to do some custom fiberglass and fit a no joke 6.5" sub in there. Although its not shallow by anymeans, the DD sw6.5 is nothing short of amazing. It only needs .33 cubic ft vented. I have one in my trailblazer, in a .456 cubic ported enclosure. WOW, if its like this in this big of a cabin, I can only imagine what it could do in a Boxster... Oh well, I'm happy it worked out.
