Is this kind of thing going to damage my Stereo Receiver in the long run?

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.

If I understand what you are doing, you are using the rear speakers for mains? If so, and especially, if they are 8 ohms, what you are doing should not cause a problem. A couple things come to mind, does the receiver have plenty of ventilation? If it's crammed on a shelf with the door shut while playing, that's no good. The vents need a couple inches room at least and either the back, front or both open. Another thing, go into your set up menu and turn off the channels with no speakers. For instance, if no center, in the menu where you have the option of saying "center" yes or no, choose no, and do the same for each unused channel.

Yes I am using them as mains The Receiver is sitting on a huge Night Stand the top of the unit is not blocked is that good enough air ventilation? I turned off Subwoofer,Center Channel and all other unused channels. I still want to have someway to clarify what ohms they are I have no model # for them. Some possible Model Numbers come to mind CRS-177,CRS-159. I even turned off the bass it says 0 on the menu options.

[Mr Peabody]

That's good ventilation. You recently turned of the sub etc. or they were always off? If always then I'm not sure what would cause the unit to run hot. The CDP is not on top of the receiver is it? If so, try putting it to the side.

[VintageTurntable]

No They weren't always off I had to turn them off. The CD player is on top of my Turntable on a Coffee Table with my ADC EQ.

[Mr Peabody]

Hopefully that will cure the problem. Let me know. Those channels were on but seeing no load so I think that might have been it.

[VintageTurntable]

No when I played it earlier those channels were off I turned them off two days ago still running HOT. The receiver has a dent or two in the case but it's NOT at all visable.

I briefly owned one of those Kenwoods and don't recall it runnparticularly hot when in use. My first suspect in this would be the speakers. Thrift stores are notorious for taking speakers frpm broken "boom box" or "all-in-one" systems and just putting them on the shelfs. Many of these speakers are 4-ohm speakers. If that is the case here, it might be a load issue that is causing it to run hot. If you have or could borrow a pair of known 8-ohm speakers you should be able to see if that is the issue fairly quickly. If it is not the speakers then I suspect there is a problem with the receiver.

It keeps on Rocking and going strong It never goes into protection,and or Shutdown Mode Just keeps on playing! I know the Speakers didn't come from a boombox or an all in one system. I don't see how they could be 4 ohm These are definately NOT CAR Audio Speakers. I ran other Receivers with these same Speakers before it was never a problem. I ran a H/K AVR-55 and another Kenwood 107VR with them.

Everything is good to go working Fantastic now! I went into menu settings and turned every surround sound option off and adjusted the distance of my mains Speakers.

I personally feel that it would be the speakers!!
Today, most speakers will have the unmeasured 8 Ohm stamped on them even before they decide which size hole to drill in the cabinet.... and some unscrupulous manufacturers even go as far as quoting the classical freq range of 20 to 20kHz for good measure.
If the speakers are less then 8 Ohms, say 4 Ohms then the poor amplifier has to put out double the current ( well almost, for this simple comparison case ). Everything in the amplifier is stressed, including the power supply. Do you get any sort of clipping effect? By that I mean the sound from the speakers begins to distort audibly, even to the unseasoned listener this phenomenon is obvious.

[VintageTurntable]

No Clipping Effect these are In Fact 8 ohm Speakers and everything works great now. No more Excessive Heat Build up or it running too hot.
