I would like to move into a storage/practice room. The owner says the power runs on a 20A breaker. We have 3 amplifiers: twin guitar combo (200 W), a bass head and cab (400W), and a pa mixer (300W). If anyone knows electricity well, I'd appreciate your advice on whether we'd be able to run this equipment. Thanks.
 
you'll be fine
you'll be able to put about 1920 Watts on that circuit...figuring in a max load of 80% to be safe

Actually, most amps have about (or less than) 50% efficiency, which means that you should do those calculations based on the consumed power, not the output power. Still, he should be fine, but I just wanted to clarify that one cannot take output watts for actual inputed watts.
 
The back of the amps should say their actual wattage usage.
