I did stereo in the glovebox and speakers in new kick panels on my statesman. Made a surround for the stereo that fit snugly in the glovebox and was secured using one of the existing screws. 2 decent speakers mounted in MDF kick panels gave good enough sound quality for me and not a single hole was drilled in original parts. Stereo had an infra red remote so I'd just leave the glovebox open if it required a lot of use. Otherwise just set and forget.
