Gmc 2024 Sierra 2024 Sound System Upgrades

Gmc 2024 Sierra 2024 Sound System Upgrades. The most i’ve done is replace head. I found sound improvement recently when i adjusted the fade more to the rear speakers on my 2020 bose system.

Coming from a 2020 at4 and a 2015 denali, i thought the sound system would be about the same. Looking for detailed help to upgrade the basic (6 speaker plus sub) bose system in a 2024 gmc at4 with the 13 inch infotainment screen.
