I was just listening to some cds when all of a sudden, my two front stopped putting out sound. The only sound I am getting now is from my sub. I checked all the connections and fixed one speaker wire that was loose, but still no sound from the front two. Is it possible that my Denon reciever that only puts out 85 watts per channel could have blown out my 12" cerwin vegas that can take at least 200 watts? Any ideas will be greatly appreciated.
