Congratulations to you as well man, great car huh? As I said in my post just above yours I did work in car audio before so I do have some knowledge. I'm a bit older now so I mainly just wanted a crisp sharp sound. I dropped a little 10in self amped sub (under my seat) and that did exactly what I wanted. So far I haven't done too much but SPT offers upgrades made specially for Subaru cars. You should check out their site or have your dealer give a brochure. It's a good place to start on mods, trim pieces, and other little touches.
