One thing...

I can't answer the question about your reciever turning off at higher volumes (although this sounds like the safety fuse is activating, so it may be a receiver problem), but on your right rear surround that's dead, try switching the rear surround connections around to do some trouble shooting. Connect the left rear surround speaker (that works) up to the right rear connection. If the working speaker doesn't work on that connection, did you do something to the surround settings on the receivers menu to disable it? Try another audio setting on the receiver to see if you can get the rear speaker to work, such as take it off of 5.1 surround and simply try 6-channel stereo, where all speakers get the same signal.

"the right surround is also dead.",,, not good!!

Excellent speakers!!! JBL is my favorite brand!
The reason it shuts down is because of an overload.
Could be a bad amp channel or speaker.
Try disconnecting the right surround speaker, see if it still fails.
If it dose then it's not the speaker. You could check out the speaker by hooking to a different amp and make sure it's OK. JBL is a very well made speaker, they can handle a lot of power before they blow out. But ANY speaker can be blown, usually the tweeters go first.
If doesn't fail then it could be a bad speaker.
FYI: Every AV receiver will shut down if you turn it way, way up. They have circuit that detects over current conditions.
Repost after you have done some checking. john

Thanks John. Did what you recommended. Its not my speakers, so it must be the Onkyo TXNR-901 Reciever. Could be the safety fuse activating even at medium high volume. Got a 5 year Extended Warranty on this. Right now, I am waiting for them to call me back as I only get a recorded message when I called their 888 number.

Check for shorts

Check your wires for shorts. Make sure there is not one strand of wire touching another terminal or a stray one laying across them. I would disconnect/reconnect everything. Also make sure you have plenty of ventilation for the receiver. Too much heat could trip it.

If it is not the speakers or the wires, it is the receiver.
