If i was you I'd build custom box or get someone to do it for me. You are not going to be able to find a box big enough to hold two L7's in your car unless you go with 10's. Actually...there are some out there but i would advise just building your own. I had two 12's in my trunk and had no other room pretty much. But just get together with some friends and build it man, I can put up a plan on the site if you want with dimensions.
