How about go to sounddomain.com? I'm sure there are a bunch of people with the same car as yours...I'm guessing and integra....that are also in the same situation as you are in now. Go to the member pages and check out some of the other teg's. Here is an example of a guy that did some kicks in his teg and still had room.

He puts his in the door area.
These are just some ideas for you.
