So I got a (free, minus $20 shipping) stock enclosure in the mail today, figured out how BMW wired the DVC subs by battery testing the signals, and hooked it up into the X using my current amp....WHAT A JOKE!!! My current dinky little generic 8 that was given to me sounds better than this thing! I'll give BMW credit for using DVC subs, but dual 6.5's...c'mon. So anyways, I felt around the box, and I can't believe how much wasted space there is around the enclosure. The back of the box got cracked in a corner during shipping, along w/ me needing to fiberglass the MDF face on anyways, but I'm thinking that I'm also gonna fiberglass these indentations and make them bigger as well. It's already got foam type stuffing in there...should I remove it and use real polyfill?

The L5 8" wants like .33-.75 airspace, and even though you said it measures out to like .5, but bigger the better, right? For those who don't have this enclosure, the 1st pic is where the airvent is for closing the hatch/door so you're ears dont pop. There is still plenty of room behind it if I unrecessed that and made it flush w/ the rest of the enclosure. The 2nd pic is for the fuel door locking mechanism, which I removed long ago when I was still fabricating a box from MDF and trying to find as much space as possible. The 3rd pic, I have no idea what that's for and it's not touching anything. The 4th pic is so you don't have to remove the enclosure to get access to the taillight bulbs. I'd rather go for the greater good and get airspace that I can use daily over function that I use once every couple of years. I know it'll be more work, but I still wanted your .02 before I started fiberglassing this week.
