Don't confuse average power with peak power. Peak power comes from caps and can be more than 15 amps but you are playing really loudly by that point. Average power will be A LOT lower -hard to say exactly because it depends on lots of variables.
Amp efficiency also plays a part, most class AB amps being 40% efficient or so. My McIntosh amp meters rarely average 30W with pretty sensitive JM Lab speakers. Factor in efficiency and the amp draws about 75W from the wall (which is less than 0.7 amps). Arthur
