When I hooked up the electricity the second time and felt the heat, the 921's wouldn't melt anything, IMO. But it's still felt hotter than I would like. So, I'm going to retrieve either some 912's or 904's from Autozone and see how those look and how much heat they generate.

That is a BIG increase in current running through the cirucit board. I'd watch it real close.
