I have 2 10" in my truck with the storage, raised my seat 4" and added 2 extra 12V outlets as well. It is a fiberglass bottom. Check my pics. I like the sound of it. Only thing is I would have gone with one ported and one sealed, as to having both ported. It would gave a wide "range" of music they can play. Dont get me wrong they sound great, Just I miss the "kick" of my normally sealed inclosures.
