whe i key up on the cb,it comes through ALL of my speakers in the runner. any help or suggestions?

Do you have a CB amp attached to it? If so, and it is on, turn it off. Otherwise, it may just be the frequency. My dads old CB used to do that in his Bronco, and also with the winsheild wipers, you could hear it through the CB speaker.

no amp installed. i am thinking it is the ground i ran. gonna re-do it in the am and see what happens tomorrow.

Id like to why also, Ive tried a few different grounds, but no change, I also hear a screatching sound when I use the winch

Dirty Power line. Run direct from Battery, Dirty Ground, Power lines running over speaker/amp lines. You may need a noise filer.

Theres a writeup on my page....

and heres a link to a good read: http://www.can4x4.com/articles/comcorner/index.htm

4Hummer,
thankx, Ill try seperating the wires, the link isnt working.

no luck here! thought it might be a ground, wired straight to battery neg and still came across. ERRRRR!

Have you checked the location of your coax? Running coax parallel or bundled with your speaker wire can cause feedback/line noise. Is your coax shielded properly or too close your radio's antenna wire?

You may want to check grounds on both your CB and stereo while you're at it. You may want to try grounding to frame instead of battery.

If you do have to run wires in close proximity or cross over each other, try to cross wires at a 90 degree angle (coax and speaker wire).

Is your CB antenna close to your radio antenna?

If you have extra coax length from radio to antenna, try to avoid coiling it tightly when you hide it. At the very least, this will help bring your SWRs down some.

Other than that, the only thing I can think of that would cause something like this is too much power too close to the radio.

Hope this helps,

All very good points. Additionally, if you are using a power mic or have the modulation level of the radio turned up, lower it.

Sorry, wrong info here. Both are old CB wives tales.
In reality,coiling the extra coax in a tight coil at the base of the antenna will create a choke that would help reduce unwanted RF radiation from the coax.
Also has no effect on the antennas' VSWR.
