    I'm running wire for a surround sound system and am worried about interferance from electrical wiring or any other sources. Is there anything i sould worry about? and if i have to cross electrical wiring is there any way to sheild the speaker wire from interferance? Thanks

    I believe the rule is to keep your wires at least 12" away from electrical wires and if you have to cross electrical wires do it at a 90 degree angle. Best to stay as far away as practically possible. Another thing I've seen others do is to buy the braided sheilding you see on coax cable and run your speaker wires through that.

    You can buy shielded speaker wire. Maybe contractors sell it.

    Keep in mind that speaker runs are large swing- they won't pick up interference the way small swing lines (like video or line level audio) will. Or, to be more precise, they will pick up the interference, but it is such a small percentage of the overall signal that you won't hear it.

    That said, avoid running your wires right alongside power lines, and you will probably be fine.
