The factory amp in my O6 Rubicon would work sometimes and others times it would not. Since it makes so much noise running down the road anyway and I mostly listen to talk radio, it was not much of an issue. However, I decided to go ahead and have it looked at.
Bad new, warranty ran out two months ago!
So if it was going to get fixed, I guess I was going to fix it! Plus the money I saved fixing it myself would easily pay for an aftermarket amp if that was what was needed.
I started with the fuses, no blown fuses, and I had 12 volts at the fuse block. So I pulled the Radio out to check the if the wiring was plugged in all the way. That was not the issue.
Next I pulled the console out so I could get at the amp. Found out that the amp is not attached to the console as much as the console is built around the amp.
Tested the wiring at the amp and had a good 12 volts at the amp.
At this point I am convinced that the amp is dead and that I will need to find a suitable aftermarket replacement. So I start putting things back together starting with the console.
Just a note: When putting the console back together, be careful with the wires going to the amp so that you do not crush them when you put the bolt that is under the cup holder back in.
Since I had been checking the voltage at the amp, the radio was plugged in turned on, and just sitting in the dash. When I got to trying to remount it in the dash, the amp started working! HEY my new Jeep has a short?
So I start pulling on the wire harness attempting to isolate the short. After taking more of my dash apart, I finally found the short.
Some lazy union worker forgot to tighten the screw that the amp grounding wire was connected to! (I don't care if everyone makes mistakes, I found this one and I get to call him names)
Best part about this is:
I did not pay the dealer $75.00 an hour to diagnose this issue.
I did not have to buy a new amp, factory or otherwise.
I got to play with tools.
I get to point out someone else mistake.
