I'm not a big fan of Bose in general (except their noise cancelling headphones), so I'm not familiar with their auto offerings. But why would a car have a center speaker? Their website tells me nothing. The only center speakers I remember in cars had AM radios attached to them. Is this a subwoofer? A phone speaker? What?

 

My wife's Terrain also has the Bose system with centre speaker, only makes sense for a home theatre system for main audio / voice etc, I recall seeing on the Terrain site that some have perhaps disconnected that speaker maybe.....? That might solve your problem and give your true stereo sound LOL

That would make sense given a lot of cars have TV screens. I didn't know the Colorados did though, so still odd.

 

Truck's a 2019, if still under warranty, let GM fix.

 

Not under warranty. After playing with it I think the center speaker has no sound except the static. Does anyone know what colour the wires are going to the center speaker.

 

Getting similar from my right rear. It’s a crap system, hard to believe they consider it an upgrade.

Bose is not highly regarded by audiophiles in the home entertainment area. Bose just saw an opportunity to jump into the vehicle market and took it. And it was successful because when it comes to Americans and their vehicles they are more than willing to pay for any shiny new object. Probably didn't hurt that the base level audio in most vehicles was crap. But back when sound systems were not part of touchscreen displays my advice was to rip everything out and replace rather than upgrade via factory.

As mentioned, I do regard their noise cancelling headphones differently, but that's based on the ability to cancel noise not necessarily the sound quality which I haven't really had the ears or time necessary to assess. And they do have a new lower priced ($800) hearing aid that looks interesting. But when I was looking for trucks and found the two GMC with all my dream options, they had Bose but that was not part of my dream options. (Although in fairness with my ears it wouldn't have been even if I thought more highly of Bose).

 

You can go in and adjust which speakers you want to listen to, I do not like listening to talk shows in stereo Black Sabath , Yes, sports talk, No

 

The centre speaker cannot be adjusted. Only the door speakers.

 

So I go out this morning and start the truck,no static. I may still go and remove the center speaker wires.

 

Listening to the same material? E.g. same songs?

 

Yes. I flipped from sirius to fm ect. and no static. Some wierd electrical stuff going on. I had problems with a service 4wd message coming on. It would sometimes come on everytime I started the truck and sometimes while just driving. Took it in and gm replaced the rear locker saying that was the problem. Issued showed up 50 miles later. They kept it for a week and gave it back to me and said they dont know what was causing the problem. Everything worked like normal and no codes so I kept driving it. Then I didnt use the truck for a couple of weeks and when I used it again the service 4wd message never came on again. Strange.

I cannot imagine how the rear locker could cause a service 4WD message.

 

They said the oil was full of metal. They checked all the wiring and nothing was worn thru. I think it will show back up once I start driving it more.

To some extent some metal is normal, but I was thinking of the G80 locker, not an electronic locker. Sorry if yours is electronic.

 

Ya it a electronic e locker(zr2). The metal comes from the hunk of metal in the center of the diff. There have been a few people with the same problem. another wierd thing that happens is sometimes I will get a email message fromonstar that there is a problem with the engine/transmission. Gm also looked into this and said nothing shows up on scans. This message has shown up around 15 times.
