Cb feedback though external am/fm speakers

I drive a 18 wheeler and use a slip seat cb box to house a magnum s-9 cb and a JVC am/fm. I hook the am/fm to the truck speakers with speaker wires from the box. When all speakers of the truck are hook up I get feedback when I key up a speak with the cb. I find that i do not have any feed back when one side of the truck speaker is not connected, it does not matter which side.

Hi Big OX,

Terrible problem.  I know what your going though.  Route your AM/FM Antenna wire, and Speaker wires separate from the  CD Antenna cable and power supply wires. If you can,  twist the speaker wires.  If the Speaker wires are run along side the CB Antenna wire for a short distance, you will pickup feedback. If you much have the Antenna wire get near the speaker wires, have the antenna wire cross the speaker wire at a 90 degree angle. Try not to run the antenna wire in paralell with the speaker wires.   Good luck

Why does the Uniden 40-Channel CB Radio (PRO505XL) "PA" acts like an extra external speaker!


nothing,thats what its supposed to do. Don't try transmitting on pa though you will blow that speaker. the type you would need is a bull horn speaker.

Too much feedback


Can you explain your terminology? Feedback or Standing Waves? Typically, Feedback is audio feedback through the speaker and back into the microphone of the CB or out of the external speaker into the mic. It can also be RF Feedback that is caused when the system. If it is audio feedback, it could be that someone has installed a T
"talk back" option and that's why you are getting feedback, if it's audio feedback.

I have a TRC 502A CB radio that hasn't been used in about 5 yrs. I recently tried to use it and when I transmitted, the audio came thru the speaker. Any idea what's wrong?


it could be grounded inside...Somebody may had it set for Talkback features.. Take it apart look for speaker wires (see if soldered to resistors) if its shorted seperate wires ..just have speakers wires attached. Try external SPKR. Try different mics or radio may have gone bad completely.

No transmit audio on my magnum deltaforce


Do you have receive? Make sure the radio is on CB and not PA. It happens. Try a different mike and make sure that is not the issue. Make sure your SWR is 1-1:5 and no higher than 2. You can loose a lot of your signal from a high SWR but SWR will not make it so you have no audio. You may have to replace the final transistor. Try this too. Take an external speaker and hook it into the PA port in the back of your CB and switch your CB to PA. If you key down your mic and hear your voice out of the external speaker your voice chip is good. Let me know if any of this helps. If I had a CB in my shop, this is how I would start the checking. Good luck.

Magnum 257 HP , no problem at all on AM or FM , modulation OK. SSB is distorted with low modulation , higher modulation seems to make it better but not consistantly . Used dummy load , BK CB tester w/2...


Nope, your not the only one. Poor power regulation internally and maybe check your antenna swr. Higher wattage with even 1.9:1 i have seen exports have issues.. and then the magnum with there alc mod (compressor) on the op amp..

With my CB I am getting feedback through the am fm radio speakers


Hello there:
the shielded coax rgu-45 series is probably the best one for this application also if you run the radio to a different fuse or u can also get a surpression filter that goes on the coax line I own a WL9000 KW. i had the same problem untill i got the filter installed at a loves truck stop in texas and no more problems since ok?
drive safe and best regards mike (warner transp.)
