Door chimes when I shut truck down

[Whitetail Addict]

I noticed today when I turn my truck off my door chime (Bose stereo) dings two times, like when a warning comes across the dic. There is no warning. I did have the batteries drain on me this weekend. Also I reloaded my tune prior to the batteries draning, same tune with minor tweaks.

I guess my question is does anyone else's truck do this? I don't recollect mine doing this before the batteries drained.
Could the batteries have caused this or could the ignition switch be bad causing the drain? I haven't had the batteries load tested yet, I needed to haul with the truck today.

Sorry for all the questions, I'm not good with vehicle electrical systems.

Mine alway chimes wen I turn it off till the key is out, then it will continue for a few seconds sometime,.

10-4, thanks.

Maybe it always did it and I didn't notice it. I'm probably being overly paranoid thinking I fried something in the electrical system.

I have been paying close attention to the dinging since last week. Most of the times it chimes twice and stops when I take the key out, every so often it don't do it at all.
Just tonight it chimed even after I took the key out, like i left something on but I checked everything, I had to put the key back in and turn the switch to get it to shut off.
Anybody experience this?
