Scott, I highly doubt that you would have had a fire on your hands due to your amplifiers. Just about every amplifier since the early 90's comes equipped with both voltage overload and high temp protection in the form of either a fuse or an actual reset breaker. Even if you had some sort of dead short going on, something would pop before you would wind up with actual flames. Even if one of your amp's output transistors had a catastrophic failure, before the fuse or breaker could pop or trip, you may only wind up with a bit of smoke, as I said before, all (UL) amps since the early 90's have the overload protection that I stated. :bigthumbsup
