98 Wrangler sound bar problems

First time posting, I have been looking at the site for about a month now.

I have a 98 wrangler that I bought 2 years ago and the sound bar has never worked. I am just now starting to get around to trying to fix it, had to work on a number of rust related problems that took a lot of my money.

I have taken the speakers out to see if they are the problem but they do not appear to be busted and I figured if I needed new speakers there would be some kind of sound coming out of them. I also followed the wires but lost them somewhere behind the radio. I do not know much about electronics so I am lost. I would love to figure out how to fix it without taking it somewhere. Any suggestions or ideas as to where to start?

Here's what i do.

1) get a speaker you know (100%) works. use that test speaker to test wires @ the music bar. (could be a front speaker if it's working and easy to remove)

if the test speaker works on both sides replace speakers, problem solved

2) if still nothing then go to radio. is it factory or aftermarket?
if it's aftermarket your Green, Green/black & Purple, Purple/black are your rear speaker outputs on the radio. use that test speaker and test the outputs of radio. if they work then have @ least a issue w/ wires between radio & Music bar. still pretty easy fix run new wires.

3) if still nothing then probably have @ least a bad radio. and would need to be replaced


to test your speakers that you removed. you will need a couple things.

1) use a multi meter and test ohm load of speaker, normal ohm load is 4 in cars, though some special factory systems will use different ohm loads, alot of times it's shown on magnet of speaker. when you test speaker you should be close to that listed load.

2) on a radio that you know works hook up speaker if it plays then your fine
if not then probably blow.

It is a factory radio. That was exactly what I was looking for. I will try that out on my day off tomorrow and let you know what it was.

for a 98 wrangler wire harness should look close to this, though the below harness is what your plugs will go into when hooking up a aftermarket radio



off that black factory plug is where your should find your rear speaker wires.

**factory wire colors should be**

Driver Rear (+) = Brown/Yellow
Driver Rear (-) = Brown/Blue
Passenger Rear (+) = Dark Blue/White
Passenger Rear (-) = Bark Blue/Pink

****warning****
Sometimes they will change speaker wire colors so be careful. i don't always trust books etc.

generally Gray plus has power, dimmer and 2 of 4 front speaker wires on it & the black plug is generally all rear speaker and the other 2 front soeaker wires.

sounds kind of simple but... on my factory radio you have to push the knob in or pull it? I don't remember... then turn it to adjust the front/back/left/right...

I only had sound on the front left, come to find out, (once someone showed me how the radio worked) it was just tuned that way. We were able to adjust it accordingly and now all of the speakers are working

And yes, I felt like an idiot... It was one of those ID 10 T errors. When you write them close together is says ID10T. like "idiot"... oops...

I checked the fade on my factory radio and it only fades right and left speakers it doesn't have a front and back fade.

I hooked the rear speakers up to the front and they worked so the problem has to be the wiring or wires. I followed the wires and it looks like everything is hooked up correcty to the radio.

I might have to take it to an audio shop and see if they can get it to work.

try a test set of wires hooked to rear outputs of radio to your speakers. if they work you can run new wires & pretty easy to do yourself, and will most likely save your self quite a bit of money. i know locally my shop is cheapest (when we used to trouble shooted a system) @ $75/hour. some places here charge $125/hour, or more. they will pretty much do what i have told you.

just a question does your factory have rear speaker wire's? even though i havent seen it much, i have seen a few radios that are only 2 channel.
