Would using 16 guage wire cause problems with my amp overloading at higher volumes? I thought I might get away with using the 16g wire to run my surrounds since I had some sitting around. One of the runs is around 50' though. I was testing everything last night and noticed my channel overload signal light was coming on at higer volumes. No where near reference level but moderate movie watching volume. I have never had those lights come on before. However, I've never used 16 guage wire either. Could these be an issue?
