Yeah, my setup is one power source from the main battery to a breakout terminal on a secondary battery in the trunk, so power isn't an issue. The V/O meter showed a solid 12 volts at the + terminal on the amp. Plus, that battery powers the mids/highs amp right next to it, and that thing is working fine still.

The fuses had continuity, but they've been in there since I bought the amp over 5 years ago. Fuses sound like a cheap investment before writing the amp off as toast though. Shit, I could just pull the fuses from the amp right next to it and try 'em since that amp still works.
