I have an issue with the radio on our 2016 SS. It is the factory radio with a Clarian amp installed and along with the factory speakers and the behind the headrest pod speakers. While I have always had an issue with "clipping" at high sound levels, sometime in the past an Electrical Connection voltmeter was installed which worked fine at first. This installation required the factory connection for the radio to be disconnected and reconnected into a subconnector supplied with the voltmeter. The voltmeter is now dead. No power. The SS was in extended storage due to health issues and I just cleaned her up and took her out yesterday for the first time in months. The last time out the voltmeter wasn't working but the radio speakers were. Yesterday the voltmeter is still dead and the radio while on produces no sound. Would that T connection failing have anything to do with this? Do the speakers output go through the radio harness or on a separate run? Hoping it is a simple fix. I did check the main radio fuse and of course it is OK. I have not checked the amp fuse as I am not able to crawl around on the garage floor and access the battery compartment and wrangle the yellow top full sized battery out. The Clarion amp is located under the driver's seat. I'm not sure if I power up the SS if I can see if any of the lights on the amp are lit up. I'm 72 years old with all kinds of joint issues. If it comes to that an audio man will get the job.
