SAME issue with my 2024 High Country. My 2020 RST was BUMPIN with the Bose system... 2024 High Country bass totally sucks.
Dealership has been useless with 5 trips. "Yes we know it sounds weaker than the truck on the lot... But we don't know what to do." -- replaced the amplifier & the subwoofer. It might sound a little better... But not much better.
They even reflashed the system a few times... Now there's popping when I'm on phone calls. Worse than before...! So frustrated...
