I have a small cheap MP3/AM/FM player with auxiliary input that I use for my computer amp. The local FM station (89.5 MHz) signal is so strong that my speakers and speaker wires act as an antenna and cause it to pick up the broadcast when I am using the auxiliary input. The subwoofer seems to be the worst offender... What can I do to stop the interference?
I have tried: 1) relocating the speaker wires 2) shielding the speaker wires with aluminum foil and grounding the shield 3) putting the subwoofer on a grounded surface (heater register)--this was about 95% effective except at times of greatest signal reflection (typically at night)...
Any cheap way to get this to stop.. ideas I have are: a capacitor across the subwoofer; a choke on the speaker wire(s), a ground wire attached to the woofer's frame/magnet...
TIA

TOROID CORES. They make different toroids with different values for different applications..that's what you need to stop interference. Try google'ing TOROID and you'll find what you need.

a ground wire may help. I had that problem with an old stereo, and grounding the frame did help. Just connect to a good ground, like the ground lug of an outlet.

We had the same problem with our phone lines and the radio station. We had to purchase a filter that we put on the phone line. We purchased it at Radio Shack.
Hope that is helpfull
