Funny guy
FYI, I'm beginning my excursion into rear fill(properly). Using T/A and bandpassing my speakers it has actually raised my stage and somewhat resolved the tweeter issue. Tweeter location isn't very good at this point but the addition of rear fill has given my sound stage somewhat of a rainbow effect now.
The rear fill has "erased" the ability to identify speaker locations though. Using T/A for two speaker setups in the front didn't seem ideal. Now with all 4 speaker locations T/A has steered the image right in front of the driver. It was kind of odd so I moved it back to the center of the dash. Tweeter attenuation helped a lot too.
Forgot to mention trunk space
Once I finalize my hardware and my installation I have plans to move and hide everything to regain my trunk. Currently I still have access to my spare.
