Is it possible for me to put a sub in my 00 WS6 in the back left hand corner and still have a place for my t-tops, or is that not possible? I'd really like a sub, but i don't want to lose my t-top holders since i take them off so much.

 

It's called stealth enclosure or stealth box. Several companies make them. Do a search and you will see dozens of examples. I run 2 of them. Here's from a post a few lines down!!

There are several more examples if you do a search!
