How much current can you draw from them? Im using a dc-ac inverter to power computer speakers... they're 200w rms, and my converter is 175w. I obviously wont be playing it at max rms so that won't be a problem, but i am worried about drawing too much current through the power outlet... how much do you think its good for? Im guessing it has a 15 amp or so fuse? I would check but i dont have a flashlight and its dark..
