For a reference point,
I actually performed a bit of a test tonight. Kids wanted to watch the Green Lantern tonight so prior to them sitting down I closed up the HT and cranked the AVR to -10. Played about the first 10 minutes of the movie which is pretty dynamic This is the loudest I can see us ever watching a movie. Awhile back I claimed only seeing between a 4 and 6 amp draw on my system. I watched it closely tonight and with an AVR that can draw 1200 watts, four subs totaling 3600 watts and about 600 watts of projector, cooling fans, BD, HD, power regulator and conditioner etc., it peaked at 9.8 amps. I was also running the subs hotter than normal. 9.8 was the peak yet it ranged from 4 to 8 amps the entire time.
