I check the other posts, now I am more confused. But I know planning before buying/installing is very important in the cars, where you have to keep your original HU.
Most of the Bimmers, choose to install a tweeter directly. I have made this mistake (in terms of audiophile) on one of my F30 with base setup. I bought harman kardon tweeters and get them soldered on front door speaker wires. Yes, sound stage increased, no worries because tweeters had hpf on the wiring, but what I did was adding more high level sound, which was already produced by our existing door speakers. Then I ended up with lowering treble from the HU. (If there is a crossover like transistor or sth, which can low pass the existing door speakers, this system may work better.)
I am planning to use rear R/L from existing HU, therefore keeping rear pdc sounds.
1) Alpine PWD-X5 is a perfect solution, dsp-buetooth-subwoofer- 4*25rms amp built in… It may push the OE speakers wery well. Also, door speakers can be updated to a crossover system. Downside is, it is just 25w per channel.
2) If It is possible to get clean signals, by coding hi-fi, maybe I can use a powerful 4ch amp, change footwell bass drivers and door components. It can also be a 3way crossover system…

I wish I had option 677 on my Z.
