I have now replaced all for of my door speakers and all clickers and chimes are working! The problem was not the speaker amp connection, simply bad speakers. My Chevrolet mechanic tells me the speakers in these model vehicles go bad frequently and he has had to replaced a lot of them. The 2007 Suburban with a plain AM-FM radio/CD player has no amp per Mr. Goodwrench. A word of advice about replacing the door speakers. The installation instructions I got from Crutchfield say to disconnect the cable that operates the inside door latch. It is virtually impossible to disconnect the cable without breaking the flimsy pastic latch handle housing. Simply suspend the inside door trim with bungee cord or similar hanger. This will keep you from breaking the door latch housings which cost $138 each to replace. I broke the housing on both of my rear doors before learning this expensive lession. I suspended the front door trims as described and was able to installed the speakers without problems.

Just a person that hates to type
Well I have the same thing going on in my 2007Avalanche. I pulled out the radio and in the back beyond the braces you can see what looks like a Delphi made amplifier I think. No numbers on the front don't show up on Google when I look for them My numbers 19032 or 15919032 Could be a numbers change by now has anybody fixed the ones posted?

May have some helpful advice
I have a 2007 Suburban. Late last week the radio started acting odd. The lights on the display would dim slightly and then be back at normal strength. There was no sound when the lights were dim, and normal sound when the display was at normal strength. IT would flicker "on and off" about once a second, then would be ok for a while then start again. It first did this when the truck was parked,(not moving the road). Driving down the road doesn't seem to affect what it is doing at all(I first thought maybe a loose connection????)
Since then the problem has worsened to the point where the radio shuts off by itself, and when on, "flashes" constantly (when lights off-no sound, when lights on -there is sound). The C/D is affected as well. I also noticed this weekend when there were still some periods where the radio worked normally, that when it was acting up-flickering on and off-, the turn signal would be visible but there was no audible "tic-tic" like there is under normal conditions. In other words, you couldn't hear the turn signal when the radio was flickering, but could hear them when it was behaving. THe turn signal lights on the outside of the truck are working normally, just no audible click when they are flashing.
Found this TSB in the list 07-08-44-008, wonder if anyone could give me more info on this TSB and where to find this amp connector it describes
Anyone had this "ghost in the machine" before?
Any ideas welcome.
