Alright, here's a good one for you folks. Purchased a 2005 Sierra 2500HD earlier this year. I Installed an aftermarket receiver, amp, subs. Used the gmos adapter (I believe) in order for the door chimes and onstar to work. Everything was working perfectly. Yesterday, my passenger hit the onstar button while we were parked. The voice came over the speakers very loudly, and I couldn't get it to stop by pressing the on star button again, so I turned the truck off. When I turned the truck back over, the door chimes weren't working, there was no power to the receiver or amp, and the onstar button and phone button on the rear view weren't working. I pressed the power button on the receiver, and that powered up, along with the amp. Now, however, when I park and turn the truck off, the stereo stays on when I open the door, and continues to stay on until I turn it off. Also after this whole incident, I noticed by right turn signal on my dash was blinking really fast like I had a short or was missing a bulb. The front and rear signals weren't lighting up, but my dash, right rear view mirror, and light bar (connected to trailer power) were all working fine. No blown fuses from what I see. I even bumped the stock 15Amp fuse for the stereo to a 20Amp, and have two fuses in line on my amp power cable that haven't blown. Any thoughts?

That looks like one hell of a problem. Sounds like there was too much power and when your passenger hit that button, it opened a gate to hell, and demons flew out to mess with your truck.
This is only my $0.02.
When your passenger hit that button, something overloaded and gave a power surge in which shorted something in your electrical system that is connected to your stereo system. To much power was being given out which explains the loudness of the onstar voice. Maybe your amp powered the onstar somehow. Maybe its all wired wrong? I know some cars you need to wire it a certain way. I dont really have any advise for you, as I hate newer cars/trucks for the complex electrics. Which is why I stick to older machines.
This is just my idea of what happend.
Start with that amp and start digging in your electric system is my advise, but thats such a headache with your truck.
Sorry wish I could help you more :/
Best of luck
