2026 Sierra 1500 Denali - Sound upgrade?

[d.lowrey]

Hi

I have a 26 1500 Denali (not the ultimate). Previously had a 23 3500 Denali. The sound quality of the 2026 is inferior to what was in the 2023. Window sticker says, "Bose Premium sound System". Does not sound "premium".

I think this is the 7-speaker system. It is unsatisfactory and I feel GM cheated me on this premium priced truck.

 

Does anyone know of a way to upgrade the system, or name of an expert installer in Las Vegas - St. George area that can do this?  Note: not interested in huge "thump" - don't want a giant subwoofer under the rear seat. Just looking for an upgrade path.

 

Thanks for your help.
