looks solid.
get some better vynl on it, definatly would look better. i like how you plan on making that center rack between the boxes, good thinking outside the box.
ive seen amps mounted under crap - i highly doubt heat dissapation is going to be a problem //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif
get them carpeted or re-vynled and it will look sweet.
and good score on the TL too - what kinda subs you got there? and do you even have a frontstage? i recommend getting one if you dont lol.
