Do you seriously think that you would ever crank the volume up so loud that you would blow a 15 amp breaker?
If you did your ears would be bleeding and the neighbors would have already called the cops!!!!!
I run my 7500 through a Monster power enter and I have never had any kind of problems of any kind and we watch movies pretty darn loud so I wouldn't worry about it.
