I have the Yamaha rx-v757 and when I turn it up really loud it shuts off. When I turn it on I get a check speaker wire message. I checked the wires and cant find a problem. Why would this happen at really loud volumes and is there any connecters I can use on the ends of the wire which ensures they are connected properly.
You may need to use a magnifying glass to look for strands?
Does the amp shows that message if you disconnect the speakers?
If you have not tried that yet, start by pulling the speaker wire at the speakers first, perhaps one speaker at a time and see. If the message disappears, at one of the speaker terminals, that was your problem.
Second, what is your speaker's impedance? That will cause a warning light at high levels and amp gets into protection mode or a warning mode.
