Let's see...
Quickie in the head math here, but it's close enough to be safe.
Ohms law states that to completely power that system you would need ~180 amps at 14 volts. Our alternators are rated for like 80 or 90 amps.
Unless you have a high power alternator and an external regulator I'd say that the internal regulator in the ECU could have died under that load and taken out the whole thing.
Rare and unlikely, but not impossible with the limited info that you've provided.
