This is the clue that tells what happened. The jacks present a high current draw on the battery. If the battery voltage is low, the jacks should draw more current than normal which, as already pointed out, probably tripped a circuit breaker or blew a master fuse located near the battery.
I'd start at the battery with a voltmeter. you should see 12V or more. Next check the distribution panel where the fuses are. If there's no voltage there, the issue definitely lies between the battery and the distribution panel.
