I have a setup that consists of 5 TVs hooked up through composite video and stereo audio. Sitting on the same shelf I have a small power amplifier that feeds 4 speakers. Whenever loud music is being played through the amp and the video is still playing, I get a lot of static. Currently in this room we have the olympics playing along with people either playing music or speaking through a microphone. I have the rg6 composite and stereo audio cables running out of the closet zip tied with the speaker wires. Could this be causing the problem?

EDIT: Just for clarification, I have a closet with 3 sources. 1 DVD player, 1 Satellite TV receiver, and 1 power amp. The DVD player and Sat. TV are hooked up to a composite video switcher and the output of that gets zip tied with the speaker wire and 1 or 2 category 5 cables before exiting the closet through a hole above the door. The RG6 composite cables run around the room zip tied to the speaker cable.

Even without running the stereo audio through the power amp, I get interference on the TVs while playing loud music. Does this sound more like a power issue? The interference increases with the volume of the sound system and only occurs in a direct correlation to output by the amp. I was under the impression that speaker cable was nearly impervious to interference.

I just recently rewired all of the TVs from rf over coax to composite because we were having this problem. Any help would be greatly appreciated.

Ok so for any other newbies who end up with this same problem, I'll tell you how I was able to fix it. I started by isolating each node of speakers to find out which one if not all, was the culprit. I found out which node was causing the problem and checked all of the wires and found that one had been very poorly spliced and the termination was not grounded. I spliced the wire correctly using solder and terminated it with a 1/4 inch fitting and my problem went away.
