SP-DA3660
Installed max11 android 11 head unit into 2016 outlander with factory rockford fosgate speakersystem with sub.
Seems only the front speakers work, when fading into back sound simply goes silent.
I've double checked all connectors etc. Tested sofar ok the steering wheel controls (except phone buttons) AC display intergration ok.
Anybody have a clue? Perhaps canbus settings? oem amp control?
Thanks!
