I have the Infinity audio system with the 10 disc changer. It has the amp under the rear seat.
My headunit is the RAZ version MOPAR P/N 56038555AM
Here are the symptoms:
When the Jeep is running I get random interference (ticks and pop sounds)
The interference IS NOT related to RPM range. It doesn't increase/decrease with an adjustment of RPMs.
It is not static
Happens on FM, AM band all stations, ALSO on CD
DOES NOT happen when motor is not running
The ticking and popping is present 90% of the time, sometimes it goes away, sometimes it is barely audible, sometimes it is loud.
- I went to the junkyard and they let me try another head unit. Thinking maybe the head unit was bad. The one they had was fully functional.
The same interference was present.
I guess it is a safe assumption the headunit is not the issue. But, what if that head unit also had the same problem as mine; since it isn't brand new I guess that is a possibility.
- Battery terminals are clean as a whistle. Wiring looks fine. Battery is fine and charges fine. Keeps 12v goes to 14v on acceleration.
- Radio wiring looks perfectly fine. I shoke the wires played with them, fiddle with the connector, etc. Everything is tight and in order and did not solve the problem.
At this point I have no idea what to try next and any help/experience is greatly appreciated!!!!
