I found the Alpine 9 speaker+sub in my old Durango to be mediocre at best. The No name but otherwise the same system in the van sounds marginally better. Just something about the midrange in that system isn’t right.
My truck has 6 speakers, 2 in the dash then one in each door. It sounds pretty good.
I had the 9 speaker Alpine in my 2021 JGC and it wasn't bad, but the HK systems I had in my 2015 and 2018 Challenger blew it away and were by far the best sounding systems I've heard in a car.
