Problem Hooking up Surround Sound, Speakers Cut Out Under Power

[dust'n the callipygous]

My parents just got some new surround sound components for their house. If there is moderate or high volume, the whole receiver cuts out.

Here's the setup:
New yamaha 465 reciever (105 watts/channel)
bose acoustimass 3 system
bose vcs-10 center channel
klipsch khc-6 in-ceiling speakers (50w rms)

I've got the front outputs from the receiver running into the bose acoustimass sub unit, which then runs out to the left and right front speakers. I didn't know any other way to hook that part up since the sub doesn't have a normal input.

The center channel and left and right rears (klipsch) are hooked up as they should be.

Not that this part really matters, but I've also got it wired with both the HD-DVR and blu-ray running seperate HDMI ins to the receiver, and then one HDMI out running to the TV.

Is it the acoustimass part screwing things up, or does my receiver just not pump out enough power for everything?

it's working now. unhooked everything and re-did it. also ran the speaker optimization mic that the receiver came with. not sure if it was because of the wiring or the speakers just weren't getting proper amounts of power. doesn't matter now though, it sounds great.

maybe a cable was touching another one, it happened to mine not long ago and the whole thing turned off with an error message saying check sp wires....(mine is also a yamaha).

Yup. Could happen again if cables or wires are touching or crossed. Most amps will shut down as the volume increases in that case.
