it looks somewhat sketchy from the pictures, you didnt touch up paint that has been scratched off etc etc, you can see the wood in the cutouts on the side.

Not shabby, but its a 3g, so its ok!

those subs must need 0 airspace, that spare tire well is only like 1.3 or so cubic feet.
Or did you build up the false floor (doesnt appear) to make more airspace?
