I had drunk friends once try to "help" by reconnecting my 2 NAD Monitor series amps after I had turned in. Turns out they had no idea what bridged mode was. No harm in the end. I think the OP fared pretty well all considered.
@perkri, I guess I needed to either put the amps in anechoic chambers or AT LEAST 2 inches of concrete, or both.
