Question about 1996 GMC Sierra
Factory Delco radio & speakers fade in and out. I turn the fade or the balance knob and it will intermittently adjust. I am to the point now where I only have the right front speaker working regularly. Occasionally the right rear speaker will come into effect, although quietly.
My personal suggestion would be to go for these repair catalogs from
www.reliable-store.com instead. much better info on all vehicles, complete details, and they also have live assistance feature

SOURCE: Installing a sub in 2008
This radio/stereo system does not have aux inputs it only has a 16 pin plug on the back and the antenna etc but not aux output connectors for an external sub woofer.
You will need to get a separate amplifier, and then wire this into it to have a sub speaker.
Also if you remove the radio you must also connect a scan tool to get the radio part number from it, as you will need to enter it back into to get it to work again.
Let me kow if you need more information.

The door chime is played over the speaker. I had the same issue the speaker was junk. The circuit resistance was correct but no tunes. Replaced the speaker with one from the junk yard and sounds great all the time.
