That's part of the alternator's mechanical efficiency no? Everything I've read discussing alternator efficiency includes the cooling losses..

The thing with electrical load is yes it puts more load on the engine but the more load on the alternator the more efficient it is, and the more load on the engine the more efficient it is so I think at the end of the day it's probably not that big of a deal.
I don't ever use the sound system though, so I'm just talking out of my ass :P
