Thanks, that's really useful. I will play with the tweeter to find the best position.

Can anyone answer any of these questions: - will a (european) 165mm standard speaker fit in the front door (Infinity Kappa 65.5cs)? - any suggestions where to place the tweeters? And how? With the least filing and sawing... - will a 130mm coax speaker fit in the rear door without cutting the door? For example with a thicker adapter ring that I could cut out of MDF board? Or should I go with a 100mm (4") speaker? - I saw in the new turbos there is a bass unit (wouldn't say a subwoofer, seems to be 6"x9" only) mounted in the cargo space. Is there an easy way to fit one into mine (Infinity or such)? Does it need an enclosure? - Where to put the amp? - I think I can figure out the wiring and stuff but any suggestions are welcome. I am new to this forum, gonna get my first Sub in a week, but when I tried the car, the stereo didn't make a deep inpact on me, so to say. Used to have a MINI, loved it, but now it is time to change... Thanks!
