subscribed, I have MY15 X6 50i with HK and this is first mod on my list.
I had a 535i before this one and I upgraded the whole system with Match 82DSP and comp speakers also match all stealth install looks 100% stock but 100% better. DSP82 is a one of the best processors, but not the best amp. with tweaking it does the job better than anything Ive heard before better than my 991 with bose.
Love what you are doing but need to find set of PnP speakers like the Focal which is probably the best on the market along with Jehnert.
Tweeter is easy, sub is manageable as well but the mid range looks different to any other BMW speaker i've seen so far.
Keep up the good work
