I can hear some stupid radio station in my subwoofer. What do i do to make it stop?

Its not loud, but I can hear it all the time for the past 2 weeks, unless I turn up the music or turn everything off altogether.

Thanx

I've never heard of anything like this in only a sub-woofer. I really doubt it has anything to do with proximity to the receiver. As someone else suggested, check for unshielded wire. I recommend bulking up all your wire. Check out Monster wire kits. The RCAs that run between units are the last thing to change. All speaker and antenna and other misc. wire is first. I use cable ties and twistie ties to keep everything reasonably organized and separated. First thing to do is keep all wires as widely separated as possible. No matter what shielding you're using, that is typically the first suspect for interference.

What you are experiencing is a phenomena known as signal inductance. You wire is actually picking up a signal, and because of the position of the wire, it is self-amplifying. Sometimes even fence wire can do this, but it has to be a really strong signal for that to happen.
Your best solution would be to buy some shielded speaker wires. The cheapest solution may be to just route the wire in a differrnt direction.

Route the speaker cables in different directions, away from other wiring, but if that doesn't work, go to Radio Shack and buy a low pass filter, that will filter out signals above 30,000 HZ. It goes on the power cable to the equipment, I think.
