I was pretty careful with the volume but did pop them a time or two. I don't think I hurt anything.

As to the SAT/Cable grounding. Our power is underground. I found that the cable guy when he upgraded our coax used the underground electrical conduit. Two of the SAT feeds are properly grounded to the ground rod, two were not grounded at all, looks like they were grounded to the rod but came off.

Of the four legs of the SAT feed, one going to the Tivo in the HT and one going to the Tivo upstairs were not grounded.

I'm correcting all the grounds later today. I don't think the cable coax was not a factor in this, it does not go into the HT, only into our office and is used for braodband internet only. But I'm still correcting it.
