I would open it, no probs, but there is a catch...
PDC sound by default is coming only from rear speakers which are even after upgrade still driven by HU directly, so believe whatever I change in amp it would affect thigs after Alpine amp eg. front speakers only.
Gong which is coming from front I have no problems with BT I don't have so can not say.
By the way, dealer ordered for me a new tweeter as they originally installed one with damaged membrane, will arrive end of next week.
Then they will also try to solve this PDC sound problem with recoding one more time or upgrading.
