Need some advice on the console I'm gonna be building for my truck.

[nicgraner]

So I'm going to be putting in a console of the rear seats of my 03 f150 screw and wanted to know what yall thought of my first attempt with sketch up, excuse the strange shapes of the "subs" scaling was weird. I also think my math is off, the square part alone comes out to like 6cubes..
