So my problem is that my Onkyo receiver shuts down everytime there is a low bass rumble.
1. The speakers I'm using are Polk Audio 5.1 RM6750. They are 8 ohm.
2. Volume is around 40+ where it'll shut off. Anything below is fine.
3. I've ruled out it being the PS3 because I'm able to recreate the shutdown with the HTPC. It appears that it shuts down when there is a lot of bass rumble.
It appears it has something to do with my front left speaker connection. Let me explain the wiring...
Surround speakers are connected directly to Onkyo receiver. Front Left/Right speakers are connected to subwoofer front/left input and subwoofer output is connected to Onkyo receiver's front left/right plugs.
If I disconnect the front left plugs on the receiver, problem is fixed.
If I disconnect the front left output plugs on subwoofer, problem is fixed.
If I disconnect front left plugs on the front left speaker, problem persists.
So any ideas? The wires look fine.

1. What speakers are you using? By any chance are they 4 ohm?
2. What is the volume level on the receiver when it shuts down? At what level can you keep PS3 to prevent the 606 from shutting down?
3. Am I correct in understanding that if you are playing the HTPC at a certain volume (let's say "50") it will never shut down, but if you switch to the PS3 and leave the volume at "50" the 606 will shut down? Or do you have to turn the 606 up to a louder volume (let's say "60") to have it be as loud as it is for the HTPC, and that's when it shuts down?
Finally, if you're using a fan, the principle in action is to remove the heat being radiated, not to blow cool air into the case. Try to aim the fan to generate airflow across the top of the receiver from front to back.
