CBRadio Tx Through Speakers

Ok so I am driving back to Sacramento, CA from Spokane, WA in a week and I wanted to fix my CB radio. I was having issues with receiving transmissions from my friend and so I pulled the headunit out(for the first time, very exciting!) and the antenna cord going into the back of the cb was loose so I tightened it. When I put everything back together, everything worked fine, EXCEPT when I transmit, I can hear it through my truck's speakers. Why the hell is that?

 

I would take it all back apart check every wire back there.

 

iv seen a bunch of cb radio questions in the offroading/trail section so i thought id give it a go. but ill take it apart and try again

 

When a high powered CB is transmitting near me I can usually hear them in my stereo speakers when I have the radio on a AM station.

But, I have never heard my own CB. Do you have a amp on your CB? Are you TX over 4 watts?

 

Well the CB was in when I bought the truck sooo I'm not sure. I'll check and get back to ya. And how do you check if its over 4 watts?

 

I don't think the cb is run to the amp
