Multiple issues with CB in Jeep

id try getting a good electronic filter/noise filter ,not sure exactly what its called, but it goes on the positive wire to the cb. or you could try hooking the positive wire to a circuit on the fuse block.

 

First off, why on earth do you think we would flame you for asking a question???????

It sort of sounds like you may be running a "vehicle fire waiting to happen," here. Hopefully, for safety's sake, everything you have wired directly to your battery is fused. If not, you definitely have a hazard.

It sounds like you are getting "ignition noise" in your CB when your jeep is running.

Aw crap, my mind is gone here. Part of the solution has to do with your spark plugs and wires. But for the life of me, I can't tell you the right terminology to replace them with. I'm sorry about that...

The other thing that comes to mind here, in addition to the filters mentioned by another poster, is to shield your hot lead from the battery to your CB. Just moving the lead to the fuse block won't help with the ignition noise.

The rest of your question may be an induction problem. Try separating the routing of all of your electronic gear's wiring.

If all else fails, you could take you jeep to a radio installation shop. But they will charge you an arm and a leg.

 

the sub may be the same thing that happens when you key up a nextel beside a small speaker it goes bezerk...

how close is the antenna to the sub?

 

Alright, As for the ignition noise, there really is nothing you can do about it except turn the squelch nob up on your transceiver.

as for your subwoofer 'popping' when you key up your radio There's probably nothing you can do about that either, the noise could be coming through the wiring from your deck to your amplifer, it could be feed through the wiring system in your vehicle to the amplifer. Try installing a noise filter going to your CB radio, and capacitor to your subwoofer amp and make sure you're using all sheilded cables to and from your amplifer.

as for your music comming through your FM transmitter (I'm guessing that's what you're using when you say rf modulator..) I can hear myself talk through my car speakers when mine is on.

Your CB may ONLY put out 4 watts of RF power.. but that's alot of power believe it or not.. I recall reading in the oweners manual to keep the wires from tranceivers the hell away from the ECU in my car.

If your SWR is less than 1.5 on the channel you plan to do the most talking, and you're getting out a reasonable distance, I'd say you have no problems.
