Ok guys. So I have decided to upgrade my stereo. I have a base 2006 Roadster. And when the top is down, the stereo is just plain crappy. I am wondering where it is safe to drill and cut in the rear wall behind the seats to mount some new componants? I need some direction on what to do as far as opening up 2 new channels as well. So give me some info or ideas guys and I will see what I come up with. Thanks
