I just had the Alpine kit installed at the dealer. It sounds much better than the base system, but I am not sure what they did coding wise. Most everything sounds a bit "bright". I have to turn treble down -2 or -3 and bass +1. My gong is stupid loud (even turned as low as it will go). I don't seem to get much sound out of the rear speakers. I have contacted my SA to see what they did.
