Largest Rear Speaker Installed??
In place of the hatch speakers. Don't think that would work to well without some fabrication. A good 6 1/2 or 8inch sub is going to be fairly heavy, and you would be hanging it from that thin plastic. And you would have to find some that are free air since they just hang in the open. Replacing all the speakers with really good ones of the same size as stock and running an amp and new HU would net you better sound. For even better, run a stealth box with 1 10inch. you'll be surprised. Good luck.
