I need to get Erin over here. He's a Room EQ Wizard wizard
Good stuff Fric!
Ok, lemme see if I can explain this.
First I did sweeps with the subs and the left midbass, then the right midbass, then the midbasses together. Each time I inverted phase on whichever speaker I was testing. I chose to set my speaker polarity based on the responses that had the most output/smoothest curve. I ended up flipping polarity on the driver midbass only.
Then I followed the instructions on this page:
https://www.minidsp.com/applications/auto-eq-with-rew
And applied an eq setting to the driver side
And an eq curve to the passenger side
Then I listened to some Muzak!
It was a whole new system! The stage widened up and everything was so much more detailed. Everything above the dash became rich and vibrant. I'm not sure how to describe it. It was like the music came from the front but wrapped around my head. I can't listen to it with out my ears perking up, it's so much more engaging.
I'm not saying that this is it. I'm sure it could be much better. For instance I noticed an imaginary diagonal could be drawn from the bottom of my steering wheel to the right of my rear view mirror. And on this line midbass comes from the left and makes a transient to upper range to the right. This was only apparent on some songs and I'm sure boils down to level matching, no?
I honestly feel like I have taken this as far as I can without knowing what else to listen for. I wish I had some essque friends nearby. I now need to audition some other cars and have some gurus sit in mine.
I'm also a bit disappointed that I resorted to the auto eq. I like to do things from the ground up and understanding the fundamentals. But I can see that the fundamentals here run deep and I have a ton of research to do. But for now I'm really happy!

I do still feel that my midbass is weaker than it should be. Don't get me wrong the L8s rattle the doors and shake the mirror but they are lacking a full and rich impact, at times I feel like I'm hearing more speaker than I am sound (and I don't mean that they locate easily). I wanna feel them in my chest. I want kick drums and snare solos to engage me. I want more realistic bass guitar. I think I have a lot of resonances in my door panels that need to be addressed first off. And my MiniDSP 2x4 is just handling the midbass and widebanders. My subs are run straight from the head unit to the amp and I think are in dire need of some t/a and bass processing. I may pick up a 2nd Mini unit. What do you guys think?
What crossover points are you running?
I know this don't sound right for 8s, but try crossing them suckers a little higher on a shallower slope. Let the pair of 15s handle some of that lower midbass. It might surprise you...I currently have the Aura 8s in my doors HPd at 100Hz/6dB, I love it.
