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.

Your AVR does have preouts ("Main outs"):

It sounds from your above system setup description that you are using the main outs from the AVR, connected to your Sonic Frontier/Aragons to drive your Front L/R speakers.

If so, then your V1000 is only driving the center and surrounds.

How long have you had this setup? Is the AVR shutting down recent?

I have had this setup about a year. The shut down has only started in the last 2 months and only when I have things cranking ...like a concert dvd. The Snell center is also 4 ohms. The AVR is rated at 105 watts @ 8 ohms. The center is
rated at 90 db sensis. and 50 watt min, 250 w max. Not sure about the Canton surrounds but I do know they are 4 ohm.

I just got off the phone with Yamaha....was only on hold for 50 minutes !! yipeeee. The tech said this AVR can be reset to 6 ohm by holding down the power button and the Straight button during power up. I will try that tonight after work.
This should help and would be cheaper than any other option
if it works.

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.
