I was tripping a 15A breaker when I listened to a song to loud, but there were a number of problems assosiated with it. To many devices running on the same circuit and old, weak breakers. It made quite a difference in my system when I had the breakers replaced and added two 20A circuits. If your house is over 30 years old and you have never looked at the breaker box, I think it would be wise to have it checked out. You may not need 20A circuits now, but you never know. I changed out all the breakers in the box added two dedicated circuits that required a conduit outside the house. The total job, parts and labor cost about $500.00. But hey, I live in California, we go through a lot of expensive sun glasses, it costs more here.
