Well none of my cuts are more than 1/16th of an inch out, I just didn't take enough time to actually design and lay out each piece, so a couple spots (Sides / back) got built on the fly. I did take the time to re-do the sides, got the port in, front wall is a bit miffed up.
It fit like a glove in the car... but took a trick or two to get it in, and a stubby screwdriver to mount the subs, so no one just gonna pop the back and walk away with it =P
This week... all week, I'm gonna take my time, using this box as a template, and re-build it a LOT stronger, add some more internal braces, and do a better paint job =P
