I find this thread very interesting. I'm glad to see somebody with the know-how actually took the time to test in a real world environment. Even though each setup can vary somewhat, I'm glad to see those findings seem to coincide with my take on the matter.

I have a dedicated 20A cirtcuit for my HT equipment, but all of my HT equipment is on the circuit, including the TV and sub. I figure this would be OK because I'm only using 6 channels on the Outlaw 770, with fairly efficient 6-8ohm speakers. I figured the chances of the 770 actually drawing more than 15A were pretty much nill, and I still think that likely to be the case. I certainly haven't had any problems driving the system loud enough to make my wife yell at me.

One thing I did do is put the 770 on its own PanaMAX 5100, with everything else on a second 5100. I figured that way I could be pretty sure of giving the amp a full 15A if it ever really needed it.
