Seems I cannot run a full cd's worth of music without the thermal protection overload shutting off the amplifier (7100 running 5 channels only). Also have blown the Klipsch RC-3 center channel speaker twice now. I usually have the surround mode set to Pl-II Cinema or Music. I ran the system at -04 volumn and after 1/2 the cd the amp shutoff. This is not the first time, so I rebuilt my large front speakers and the center channel(out of necessity) and it again happened today. Could the center being blown cause the shutdown? or maybe I need a fan for cooling? I have a fairly good passive ventiliation closet setup. Any suggestions pals?
