Speakers cut out

20

Asked by Apr 16, 2014 at 10:50 AM about the 2008 Jeep Wrangler Unlimited Sahara 4WD

Question type: Maintenance & Repair

The radio in my Jeep will play just fine for as little as 30 seconds to ten minutes or more but eventually all of my speakers will suddenly cut off.  The radio is still powered on, only the speakers cut out.  It's all or nothing, either every speaker is working just fine or all of them cut off at the same time.  I turn the radio off for a few seconds and turn it back on and they work again for a short while.  Any ideas?

I have had the Jeep for 4 years and never had a problem until the last couple of weeks.  I had some water issues with the top leaking and thought it might be a short but wouldn't the entire radio cut out/off if that were the case?

My neighbor mentioned that I might need to check the connection behind the radio and another friend thought it might be that the radio is going out and overheats or simply can't power the speakers after a while.

You may have a speaker or speakers coils that are bad and going over ohms causing the output transistors to overheat and shut down, eventually they will go completely. Speakers don't like water so check the speakers to see if they have been wet

I found something online that suggested I remove the negative post on the battery for 10 seconds then replace. That apparently resets the computer. I tried that earlier today and have not had any problems out of the radio or speakers since. Not sure why but it seems to have worked.

If you have a hard top, check the electrical plug in the back, next to the washer fluid line. If that connector is dirty or not fully locked in place, it will cause the speakers to cut in and out. Especially on rougher roads. The radio also has a volume control feature reliant on that plug. Another symptom would be if the volume sometimes gets louder or lower in a kind of wave.
