I lost about half bag space with just the 6's. Then lost another quarter by adding the 6x9 lids. So basically I can fit gloves, a hat and small tool bag in there. I cant fit my helmet anymore which kind of sucks. That is with my stock bags. If you went with the stretched bags would would have more space.

 

My mechanic has JL mid drivers in his bags. Spent much less than 2k and they sound great! 2k is kinda steep, it's like paying 600$ per sub.

 

I guess your right the price of their subs has come down since I last looked at them......you can get one of their w7's for 1300.00 lol
