I have a 2004 Wrangler, had issues with the radio speakers since I got it. Only two out of the four are working, but what’s strange is the two that work are opposites, the left dash speaker and the right overhead speaker. I can very faintly hear a slight popping sound coming from the left overhead and I can just barely hear the music playing but extremely distorted and crunchy from the right dash, but it’s so faint on both that you have to fade and balance to just those speakers and put your ears up to them to hear it. I checked all wiring and nothing looks broken or anything, could this possibly be a radio issue? Radio is the factory one, nothing is touched.
