Either side of the hatch/trunk makes a good spot to build a glas' enclosure. The irregular shape of these corners offers a lot of air volume for a sub when you can sculpt the box to fit the car. If you need some tips, just e-mail me. Getting started doing this just takes some nerve and patience. Most any competent body shop can handle the finishing details for you.
I have attached a picture of the beginnings of making a mold of one of my hatch trim panels. I will be glad to explain the process.
