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.

I think you need a more powerful amp, more efficient speakers or you should learn the limits of your system.

Just to stir the pot a bit more.

The OP may be able to keep his current AVR and IF it has pre-outs, he could add an external amp.

Couple of choices:
1) 2-channel ext amp for Front L/R speakers - which may 'offload' the AVR enough to drive the remain speakers
2) multi-channel ext amp: 3 or even 5 channel and completely offload the AVR from driving any speakers.

Would be helpful to know which Yammie AVR model the OP has.

I still have my Yamaha RX-V1800 as my AVR for a 5.1 setup. At one point I had my old Carver M-1.0t hooked up via the AVR pres for Front L/R ext amplification, and could go "stupid loud" for all channels.

I have the Yamaha RX 1000. Not sure if it has pre outs as you mentioned. The Sonic Frontiers preamp has a bypass switch so the mains are running off 2 Aragon Palladium monoblocs. The Sub is self powered and the Yammy is also running the center.

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?
