I bought a yahama Rx 373 the other day and hooked it up and every time I turned it up it switched off and said "check SP wires"
I googled and troubleshot by disconnecting all speakers and connecting one at a time. Finally found it to be the FL one. (I had no sub at this time)
I swapped the plus and minus connector round for the FL and problem solved ie can turn up loud.
However I just bought and connected a sub via RCA connection and it switches itself off again and check SP wires....
Please help as I cant see how the sub would make this happen as no frayed wires or no option to connect wrong way round ?
I have the rca cable going from sub out on av to right in on sub which I believe to be correct?
