I have some questions about mounting ML 500R in MLK system?
I wounder where is the best spot for me to place this ribbon mid/tweeter?

my car is BMW E46 316 compact

the tweeter will be in original place and ML1600 in the door

I will go passive with this system.

the sound stage/image isnt the most important! the sound is the most important.

my setup looks like this

Audison Bit or Eclipse 8445E
ML 2500
