2021 TB Zues Bronze Activ
I don't think I have the Bose system. Not listed out on my window sticker, nothing in the interior of the truck saying so and I have the speaker on the spare.
There are 3 different sound systems available on the Trailblazer, 4 speaker, 6 speaker and 7 speaker Bose. The 7th speaker in the Bose system is the spare tire subwoofer. It's possible some people got the subwoofer without the Bose system who also have AWD. ANC (active noise cancellation) is standard on AWD models and might require the subwoofer in order to cancel out unwanted low frequencies. The "pre production sample" sticker is still a mystery. In any event consider it a bonus if you have the Bose subwoofer without the Bose system.I have not taken it apart to check. What does it mean if it does have that sticker?
Would you happen to remember if the one you looked at was an AWD model?So I went to my local dealership and looked at a LT with no options.
When I looked under the spare what to my surprise, There is a little speaker!
So it's safe to say they all come with the little speaker under the spare tire.
