Sound System silent when cold

[29tomt]

Have the same problem when its cold outside no sound! I pulled out the on star chime amp behind my head unit wiggled the wires and kept messing with it and the sound came on. Hoping this is the problem and I will update after a replacement is installed.

Did you find the problem? Tkx

Did anyone ever solve this?

I have sometimes as well the problem, when I start the truck that I have no sound at all. Radio is on, but there comes no sound. I switch of the truck, start it again and the sound is there.

That happened more in the winter, when the truck was cold, than now, so my suggestion is, that there is probably a small relay on the board of the amplifier, that stuck at this moment.

Does anyone know how the bose amplifier is switched on by the radio? Ot is it startet from ignition?

Another case here. It is all of my speakers ONLY WHEN COLD. I am sure of this.

One symptom I have is there is a faint (consistent) popping noise from the speakers.

If it was a single speaker connection it would only affect that one speaker. So must be something in or connected to the amp. The amp is so hard to reach I am reluctant to troubleshoot that. What would one do other than check/tighten wire harness connections? Cut back, and re-pin the harness terminal?

After tolerating this for a few years now, I decided to put my mind to it and make it a project. I removed the bucket from the center console so I could see the Bose amplifier underneath and put a hair dryer to it and sure enough after about 3 to 5 minutes of applying heat the radio started playing. I waited til the next morning and turned on the radio - nothing. Now I unplugged and plugged in the connectors a few times in case the problem was with the connectors and maybe some corrosion, but that didn't make a difference. Then I applied heat again to the heavy aluminum body of the amplifier unit away from the plugs and 5 minutes later the radio came on. Now I was pretty much assured that the problem was with e Bose amplifier. To my surprise it was very easy to remove the amplifier from the center console. There are some really good help videos on YouTube on how to remove that baby. You don't need to remove the center console to do this. Undoing the connectors is easy and so is unscrewing the 2 rear mounting screws for the amplifier. They are easy to get to with a 7 mm socket and a long extension. But the 2 front screws are not that easy. You need a 7 mm wrench to get to them and you work strictly by intuition and gut feeling. It depends on how talented you are how long it will take you to get them out. But you will not get them back in unless you make it easy on yourself and drill 2 holes in precisely the right spot through the metal frame above it (see attached picture). Once you have done this it becomes relatively easy to install the replacement unit. Follow the tutorial video, there are a few other tricks you need to observe. I went to the local salvage yard to get a hopefully good replacement and I did and I had this thing out of the donor car in 20 minutes flat and the thing works like a charm. After all this time problem is finally solved.
