Does anyone know the best way to put two 12" JL subs under a seat? I have an '00 Jeep Grand Cherokee and I have a feeling I'm going to have to make two custom fiberglass boxes...I've searched for custom boxes but they don't seem to exist. Also, if anyone else has any other ideas on how to accommodate two subs somewhere else than my trunk (I have 3 JLs back there) or under the back seat, it would be greatly appreciated. Thanks.

EDIT: I can also reverse it (put the three 8" subs under the seat and the 12s in the trunk) if that makes the process easier...
