First of all, are you sure you have the Bose system? Also, you should test the speakers to make they are OK.

My Cadillacs do not say "Bose" on the face. Not that we are comparing apples and apples, but just because your radio doesn't say "Bose" on it may (may) not be a deciding factor.

Interesting..... stereo fixed itself
My left front speaker worked the other day then stopped, when it was working my open door beeps worked also;
I decided to open my driver door panel without disconnecting window controls, just wanted to see if maybe a bad ground on speaker.
well the moment i pulled the bottom out everything started working , I snapped back in place and it has been 4 days now , stereo, open door beep all are still working
guess i will wait it out before going further LOL

I'm having same problem. Front driver speaker comes & goes. Both rear speakers never play at all. I just installed aftermarket double din & interface. It didn't change anything, speakers still the same. Where is the factory amp?? I have 07 Trailblazer LT 4x4

If you have one it is behind one of the panels in the rear back sides , on mine I had a space on the drivers side, it is very easy to remove these panels , If you have a amp let me know, I bought one then found out I don;t have one.
I did not have one. I am also having the same speaker problem , I think it is a ground wire as mine is intermittent. I stated taking the door panel off the left front and they came on
then next day gone again. I was just driving back from a trip and they all came on until i stopped and got gas, then off again. One thing i did notice is that my open door chime also does not work when the speakers don't. I have wiggled the wires in the driver door but that has had no effect.
I am looking for a schematic for a common ground between these two things
