Going install some rectangular in wall speakers...Am I going to have a problem if I only have 1/2" of dry wall between one edge of the cut out and a stud? The installation instructions calls for a minimum 1". I figure I won't beable to completely engage the rotating cams, but they will at least be half way engaged. Keep in mind the other three sides will have plenty of room for the rotating cams to be fully engaged. Anyone run into this issue?
