Help connecting CB speaker

Your post was very confusing to me at first, then I realized you were talking about the cobra speaker with talkback. This is the only thing I could find on it.


“That's right it's 10 years later. I found the answer to this question and I will share it. You plug the black wire in the external speaker Jack like normal.

The red mystery wire is actually an antenna and operates on the principle of a bleed-over. Just like when you use a CB too close to another radio, you hear the CB coming over the radio or an old television set. The red wire is to pick up bleed-over and send it back to the speaker. Mount the speaker and then run the red wire through your headliner as close as possible through one antenna or the other. It's best if you can plug that red wire into your PA Jack on the back of your CB, though it is not necessary. If you are using the PA, send that plug as far towards the antenna as you can to help pick up the RF power radiating from your CB and leave it unplugged. The red wire takes your voice back to the speaker where it has a circuit board that amplifies your voice that's creating a talk back. Don't get too excited because it will not be as loud as a TalkBack built into your radio but will serve you well if you use this speaker as opposed to modifying your radio.”

Hope this helps.
