System shutting down due to clipping?

From time to time my HT system shuts off when playing at higher volumes. The Yamaha AV unit is running out of juice and I assume it is tripping off as a self preservation function. I am guessing that the rear surround speakers are the culprits since they are 4 ohm. I am not sure whatload the center channel is.
SO how do I fix this? I do not want to change the AV unit and am not real keen about changing the speakers either. Don't even think of suggesting that I turn the volume down.

Maybe the AVR power supplies are failing....it is an older model.

If you've had this for awhile and the shutdowns are 'recent' - sure makes the AVR the probable culprit.

Good excuse for an upgrade!! :-)

This is not an "older model" New last year. Still under warranty.

Well you didn't say the exact full model number.

There was an older RX-V1000 that IS obsolete/discontinued.

The newer Aventage line is the RX-A1000.

Like I said in reply #1 - hope the 6-ohm setting works for you... ;-)

I was able to reset the avr to 6 ohms. At high volumes with dynamic passages it still will shut down. I think I need an extra amp for the surrounds only or else replace the speakers with 8 ohm boxes.

OK , the system still shuts down at concert level volumes. Strange thing since it never use to do that before. It has been reset to 6 ohms but that made no difference.
I may try hooking up the old NAD 2700 amp I had before to see if that would cure the problem. I have to get it back from the guy I traded it to months ago. I still wonder if the AVR is defective. I do hate to ship it back even if it is under warranty.
