Enclosure help.
 

I"m working on an idea for a simple and clean enclosure for my buick century. I just want opinions. I'm going to be running 2 10'' Jl W6's, and what I was thinking was to make a custom enclosure for my 6x9's in my rear window. and where the 6x9's are regularly mounted, I wanted incorporate the holes as my port's. If this makes any sense??
