Matt. I can definitely say that crossing higher, HP~125hz @12db slope, and modifying the stock "baffle" fixed a lot of problems with my install. Stock doors actually don't do bad with my 1" tweeters crossed in the upper midrange mounted in A pillars. My stage height is just above my dash in most cases unless I get a guy with a real low voice.

There's always a compromise But the DSP for rear fill REALLY helps zero in on my front stage install compromise. I used time alignment and bandpassed the rear speakers for mid-range only. I attenuated the right rear a bit higher than left rear and you can literally "see" my stage move across the dash when I made those adjustments. I really don't see how to mitigate install problems without DSP when trying to keep your setup low key. I just really don't like advertising what I have and what it does. The only prominence is my 9887 and the tweeters in the A pillars which don't really scream "bad ass" in any way. The key to a compromised install is using reflections.
