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.

I’ve heard similar complaints from newer vehicles where the factory “premium” systems don’t always live up to expectations. A good installer should be able to improve the sound without turning it into a bass-heavy setup. I’d look into upgrading the front speakers, adding a quality DSP amplifier, and possibly improving sound deadening first—those changes usually make a much bigger difference than just adding a subwoofer. Hopefully someone local can recommend a reputable installer in the Las Vegas/St. George area.
