CB Out to Aux in?

Does anyone know if this works?

I mounted my CB under the driver seat, yeah it's hard to get to but I wanted it out of sight. Basically the same concept as the footman bracket, I mounted mine to the cross bar under the seat to keep it up off the floor.

Anyway, does anyone know if I run a cord between the CB Speaker output and the input on my radio Aux In will it work?

Probably not, those are preamped for a speaker as opposed to a simple line in which should be a lower wattage than the speaker would draw... simply put it may cause damage to the input by giving it too much juice... but I am a bit beyond my knowledge here.

Best I can say is I would not do it. I'd just get the external speaker and mount it to the roll bar, doneski.

+1 on the external speaker.
You can use a line level converter to drive your AUX input. They are cheap and would feed both channels.

If it is a speakers output, no. If it is a line level output, yes.
Strange thing though. Our cell phones are speaker outputs, and we use them for
AUX IN on our car stereo's. Therefore, I think if its the same plug, meaning 1/8" stereo, it is okay.

Thanks for your replies. I have no understanding about this type of electronics.
I'm not opposed to installing an speaker in the roll bar, just looking for an easy fix and it seemed obvious to me to use the AUX IN, but since nobody seemed to post it earlier I figured it probably wasn't an option. I had to ask anyway...

Cell phones are not "speaker" out, they are headphone meaning low level adjustable opposed to fixed line.

Send a PM if you want a simple parts list and diagram.

I think they are called headphone speakers. You can plug speakers into them and adjust the volume.

If the CB OUT has the same size and type plug as your AUX IN you should be okay. Just watch the gain on the CB volume and don't turn it up so high that it starts to distort coming out of the stereo.

Also, check to make sure that the CB OUT is a stereo out and not a mono output. If it is a mono out, them you'll want a stereo to mono adapter.

So, finally got home from business trip. Went out to the jeep this morning and ran a 1/8" stereo jumper between the Ext. Spk. OUT of my old RS TRC-443 and the AUX IN on the stereo.

Simply put this does work.

Most likely I will install an External Speaker this winter just for peace of mind.

Depends on how you define 'work". A paper clip will work in a 110 outlet - try it, it fits.

You turn up the volume just a little to hear a weak station and the guy from S.A. comes up with 10 million watts and his rodger-beeping amplified D104 is now feeding 12 volts (unloaded speaker level that should be driving 4 to 8 Ohms impedance) into an input designed for about 1.1V RMS max. Might not fry your AUX... This time.

This is the same deal as adding an external amp to stereos that don't have line outs. Gotta properly match levels (and hopefully impedance).

Understood, I do plan to install the external speaker on the roll bar and leave the aux in for my phone or MP3.

Thanks for the help.

Your right! The paper clip makes a neat sound when you put in the wall socket.

You haven't mentioned what model or Year Wrangler you have, but there is a thread that talks about a fix to the sound level decreasing with the top off.

Here is the video.
JK hardtop remove sound fix. - YouTube


And here is the link of the other fixes and the thread discussion. Hope this helps.

If you hear sound from both speakers you are fine. This means the CBOUT is a stereo output. If it is a 1/8" stereo output, it is correct to use a stereo 1/8" line in, like your car stereo. Just watch the gains(volume) on your CB.

If you are hearing stereo sound, you wouldn't want to use a single speaker, because that would be mono, and that "would" destroy the circuit if it is a stereo output.
