CB and Stereo
Not sure you can. You could reduce the power of your transmitter. I heard of a guy that had so much transmitting power, he could pull up to a carwash and tap his CB and coins would come out. Speakers work the same way as coin dispensers. It is illegal to have TOO much transmitting power as well as stealing from carwashes.
You could sheild all your speakers with copper mesh and ground it, that would trap the EM signals.

I have the same problem. I have two tens and whenever I key the mic my subs pound! A few people told me to get some high dollar rca cables and that it might fix it. A few people have also told me that you really cant get rid of the problem totally.

When you key the mic with the amp off and the speaker stills makes noise, you will not get rid of this, w/o the sheilding I was on about above. You don't really need "high dollar" rca's, just good ones with good sheilding, but I doubt that is the culprit unless the problem happens only when the amp is on and not off.

Well, if thats the case, then your amp is amping the signal. It could be coming in anywhere. Try upgrading your rca's, I guess. Could sheild your amp with copper mesh too.

I had this problem, so I ran the power and ground wires for the CB directly to battery with an inline fuse, completely stopped all problems!! Give it a try, it has been known to work for a number of people.

Your amp's power needs will dictate the size of your cable and fuse. I think my Palomar 250 was hooked up with 10 ga multistrand and a 30 amp fuse in the last truck I had it installed in. I havent played with CB in a while...
Yeah, power amps will do all sorts of wierd things, we used to talk on the drivethrough order speaker at MacDonalds and I have heard myself on peoples stereos parked next to me at traffic signals, and of course the neighbors telephones and TV's. You can avoid some of that with a clean radio (no limiter clipping and dont go too far on the mod adj.) and dont run a high drive radio into the amp, that seems to increase bleedover. I had a variable power control on my radio, ran it high with amp off, low with amp on. The higher quality ham-based radios seem to have less problems with bleedover. My friend hooked his stereo up on a switch on his mic, whenever he keyed up it muted his radio, that took care of the interference problem.
