Depending how your wiring is set up and if you use bare wire to the terminals, the speaker wire would be your back up
I was nervous when I originally set up my VP150 above my tv. Not only would the center fall but it would land on the back of my rptv and possibly smash the mirror. It's been up there on the FMB for quite a while with no signs of problems. My wire is ran through the walls and looped on a stud I think that it would hold if needed.
