Here's what I did to resolve the issue.
Problem:2013 chevrolet silverado lt crew cab presents intermittent volume. Left front door and pillar speaker finally completely quit so no door chimes or turn signal sound at all.
I ordered the jbl 600c component for the front and jbl 602 for the rear doors, verified the front left woofer was toast, but the pillar was still intermittent, after doing the complete speaker swap on all 4 doors and both pillars the volume would still come on and off. I checked all pins on the speaker side wiring and verified continuity with a multi meter, which left only the head unit connectors out the head unit components.
Resolution: removed the plastic cover for the unit, found small piece of foil cable shielding fluttering around, also noticed when powered the right side would get very hot. This is where the heat sink (no fan on the unit) attaches and has thermal compound to the chips. There was excessive compound that's smooshed over the edge and contacting the pounds going on the board for the chips. Removed compound with alcohol and a fine brush, cleaned surfaces and applied artic silver correctly and put plastic shroud back in place and reattached heat sink, all has been fine for a week now and the radio functions as designed, no drop out or loss of chimes.
Before you drop $$ on a new head unit try this first, I still recommend the speaker replacement as the new jbl set only cost me about $90 and Crutchfield throws in the speaker adapters and wire terminal adapters with the package.

I tested each speaker 1-by-1 and all works. I also turned off the "Auto-Volume" with no luck.

While driving, suddenly I get bass, the music start to sound good and the volume gets hard that I have to turn it down a lil bit.

Anyway similar occurrence...?

It may just be a wiring or connection issue. That is just a suggestion, not a diagnosis. I encourage you to take the vehicle in for an inspection. A certified technician will be able to offer a more accurate diagnosis after a physical inspection.

Please keep us posted. If you have additional questions, please feel free to contact me.

Have you had the vehicle inspected for this issue?

Instead of telling folks to through good money after bad and go to a dealership that will drain your bank account, why don't you tell us what Chevrolet knows as the problem and the fix?
