Alright I did a search and came up with nothing, but does anyone know the rough inner dimensions of the storage bins?

 

Not good for a woofer enclosure if your'e planning on it. I'll measure tomorrow morning should be warm enough =)

 

I plan on taking the bin al the way out once I get the car, and having it angled slightly so it doesnt fire straight into the roof.

 

Then you don't really need measurements. Once you get the bins and carpet out, you'll see what I mean. Chances are you will need to rework the bin framework to get the angle you want. The hole in the framework is about the same size as the carpet insert on the bin lids.
