Hm, today after some futher testing i changed the coils back to 0.27 mH coils and left the caps 6.3 uF.
And found something interesting concerning the stock wiring, i didn't notice before.
The BOSE 3" speakers are both in phase. The tweeters seems to be out of phase.
At the moment i have no tools to test the polarity of the tweeters.
The HEAS 4" speakers are different. Left is in phase while right is out of phase. Tweeters are a reverse polarity in comparison to the mid speakers.
Why is one HAES mid speaker in phase and one out of phase? This seems strange to me, because they both are directed in the same direction. And why are the tweeters also both out of phase compared to the mid speakers. Makes no sense to me.
Testing the speakers alone outside the car, the in phase speaker sounded better. So i will do both mid speakers in phase and both tweeters out of phase and test that in the car tomorrow.
