Question about Pioneer Audio Players & Recorders
The AMP-ERR message in many Pioneer Receivers is caused by some DC in the output. The microprocessor then issues the warning and shuts the unit off. It is definitely not a relay switch. It could be the amplifier power pack, i.e. PAC011A or similar that is faulty or something else. Not easy to repair for the non- experienced DIY.

Aside from any intrinsic problem with your receiver, the usual suspects are;
1) Poor receiver ventilation. 2) Very high levels of bass. 3) Shorts in the speaker wiring. 4) A rubbing loudspeaker voice coil.

It is possible then that the root cause may not be electrical, but acoustic if you're noticing the issue from your listening position.
If you can run a channel test signal identically one channel at a time by positioning your meter less than a foot away and exactly the same distance with each speaker and the level differs by more than 1/2dB, then it's not the acoustics.
