I'd start with a stud finder and the book "Dare to Discipline". If the book doesn't work, hit 'em with the stud finder.
I Need to Mount Amps ON WALL+++
Any suggestions for racks that are designed to mount on the wall? This is the only solution to keep expensive , hot components away from the prying hands of my two youngsters. I have looked through a few catalogues (audio advisor, music direct) with no luck. I suppose I could rig a floor rack........thank you....Mark
