Is there a difference in 2019 and 2020 Sierra Bose Audio?

[stepaul8]

I turned in my 2020 Sierra SLT with Bose audio yesterday and got back a 2019 Sierra SLT with the Bose audio package. Is there a difference in equipment? It sounds a bit different.

Welcome to the site.

 

In the K2's (14 - 19 LD) there were 2 versions. Low end was a 6 speaker (no sub), and the higher end was a 7 speaker version (added sub in center console). 

Not completely sure about the T1's.

In the '20 order guide there was a 6 and a 7 speaker system -- but it only labels the 7 speaker as Bose 

 

UQF    Audio system feature, 6-speaker system
1 -  Requires Crew Cab or Double Cab model.

 

UQA    Bose Sound System, premium 7-speaker system with Richbass woofer
 

 

On some trims the 6 speaker was standard and the 7 speaker was optional.
