There is so much midbass actually need to decrease underseats by some db-s. These underseats are nuts!
What i forgot to mention is that "remote in" wire is not required. (Only for setting up DSP - first turn on)
DSP can sense speaker line and automatically turns on. It was called "Autostart" feature in settings.
Also, automatic turn off when no sound is coming. It was 1 minute delay that is adjustable.
Rear speakers are connected to car HU. Now they play rather pleasant while only ones connected.
Still they don't make much difference, only for rear passengers.
At the moment it feels like soundstage is infront of you. You're like driving towards the music. Which is something have never ever felt before.
Can't believe this already fantastic setup can be improved even further with EQ.
Not sure if it's worth to add subwoofer to cover anything below 60hz. Perhaps if infinite baffle setup can be implemented with some shallow 15" sub. Retaining ability to fold down rear seats.
Some useful pointers from the pdf document.

We should avoid driving the speaker at or below Fs. For tweeters, 1.5 to 2 times Fs is a good choice.
For midrange and midbass speakers, crossing at Fs (ideally a little higher) is OK so long as you’re
using steep crossover slopes
24dB/octave Linkwitz-Riley crossove preferred when crossing speaker crossovers to cancel out any phase shift.
However in reality reflections cause phase shift which can be mended with EQ
