I have a Sony DG910 receiver. Up until now I had been running a 6.1 system using all infinity bookshelf speakers, center, and sub.
I got 2 Polk Monitor 50's last week to replace my 2 front speakers and I moved those to the rear to get 7.1 running. Ever since hooking them up my receiver goes into Protect mode and shuts off if I turn the volume up to even mid-high levels. If a scene gets loud, it definitely will shut off. I ended up having to take the M50's out of my setup just so we could finish a blu-ray last night.
I used an ohm meter and tested the same wiring from the receiver end to my 2 front Infinity's and got 6.8 on each. I then put the Polks in there and got 4.0 on each. Is this my problem? Will the M50's not mesh with the rest of my speakers and keep causing the Protect mode issue? I just ordered 100ft of 14 awg speaker wire to replace all of my wiring, and ordered some banana plugs too. I want to eliminate all other possibilities before knowing for 100% sure it's the M50's.
Any tips, suggestions, advice, etc on this issue would be GREATLY appreciated. Thanks!
