I have a Kenwod VR-309 I don't have any front Speakers at the moment and am unable to buy any right now. So anyways I hooked up these two Kenwood Rear Surround Sound Speakers I found at a Thrift Store and I keep the volume between 20-27 and noticed my Receiver was getting hot I only played it for a couple of hours today at this volume level. Is this going to damage my receiver in the long run? It has never been a problem with other Stereo Receivers. My VR-309 didn't go into protect or try to shutdown on me. I just played some CD's on my Teac CD Player. My Speaker Wire is NOT too thin. The Rear Surround Sound Speakers appear to be 8 ohm. I wouldn't even think about hooking up Speakers or Subwoofers that are designed for Car Audio.
