So...I just sat in a brand new 2021 GT1 which had the 9-speaker stereo system, connected my phone via Bluetooth and played around a bit. Sound was very good IMO.
I know that for 2021/2022 Kia moved the 15-speaker harman/kardon to the GT2 trim only.
Gotta say though...I was plenty surprised by this 9-speaker system, for what I need it was great.
Now I'm back on the fence, and very tempted to contact my Vroom rep and get into the GT instead. Really don't need the sunroof, I have Google maps via
Android Auto for nav if/when I need it, and I reallllllly like this car sitting on the OEM 19's instead of 18's.
Ugh!
