Started long ago with the stock nav stereo. Lost all audio (good power, nav controls, etc.). Replaced with a Clarion and worked fine for a few years before the same thing happened. Just got a new Insane Audio system and installed it today, no audio. I’ve verified the install is correct and wired up properly. The Jeep side of the connector appears clean and operational. Is something upstream from that connector a common fail item? Something that would cause the loss of all the speakers?

Could it be a bad amp? Does everything run through the amp?

Thanks.
