Regarding your home theater installation, you can also hide all your front wires by drilling a 1/2" hole behind each front speaker and dropping the wires behind the wall instead, comming back out behind the cabinet..spackle, paint, done... you can do this with an electronic stud finder ( $ 15.95 @ the Home depot) and a 4' fish tape or coat hangar. with the 16" spread between studs, you have a good shot at a much cleaner install.....
