Does anyone know if there's an easy path to upgrade from the standard audio system to the premium factory system? I know there are some wiring harness differences to accommodate the extra speakers and amp, but I'm wondering what the chances are that they built all cars with same harness (which would make an upgrade fairly easy).
Better sound would be nice, but even more important is keeping our car as factory stock as possible, so things like external subwoofers aren't an option.
