Speaker wires near AC wires

Cool...thanks.

No problem with the FM coax. Many FM radios use their line cords as an antenna.

While on the subject, I'm also running an antenna coax cable to my tuner in the same proximity. Does that pose any potential problems?

Thanks guys...that's what I was thinking but wanted to make sure.

I agree with Mapman -- nothing to worry about. Four inches sounds like very reasonable separation, especially where the length of the parallelism is small. Also, the very low impedance levels of an amp/speaker interface, and the fact that there is no subsequent amplification further downstream, both minimize sensitivity to emi (electromagnetic interference).

Doesn't sound like anything to worry about to me.

Running speaker wires parallel and very close to AC wires would be something to avoid perhaps if at all possible.
