Hertz HSK won't Tune Right

Oh no... this is the 4th attempt with tweeters (in A-Pillars) and raising soundstage, still improvement active over passive, but no matter how I tweak EQ and TA, I still can't get it to sound right in my pathfinder, just tiring on my ears, and loud & detailed, but just doesn't sound full & rich. Always a harshness & can't attain a smooth sound. My prior setup before the ongoing attempt to duplicate that, was actually a set of eclipse 5 1/4" components which shouldn't even touch the previous Morel Hybrid Ovations I tried or these Hertz...
It's really mind boggling, but I just can't get it right, no matter what just doesn't sound smooth, warm and full like the old setup. I had the tweets actually mounted down low beside the mid but aimed up so they were reflecting upwards off edge of dashboard into cab and it actually sounded pretty awesome. Nice and smooth through full range, stage was slightly lower, but at middle and higher volumes, it came up nice and high. Now all these higher tweeter mounts and active setup and everything just don't get me that nice blend... Any suggestions, should I take these and mount them low like before for my vehicle since nothing else has worked?

before moving them, try dropping 2-4 db in the 4-8khz area and add maybe add a touch of lower midrange 250-500hz. Maybe just a thought. Smoothening out crossover points will take you a long way as well. Sometimes the slope and the freq point adjustments can be more beneficial than all the eq work in the world.

Ya I've tried dropping attenuation to different amounts all the way to -9 on both sides, tried couple different crossover points, found 4khz to be best out of options. Have been using 24db crossover on top of mids and bottom of tweets. Tried adding a bit in those 300-800 ranges and dipping at 3khz-8khz, but then it just quietens range and makes it sound hollow where it should be full and smooth to me and just causes me to turn volume up louder which still ends up leading to harshness, and lack of blended sound. I have acute ears and seem to pick up the large separation between tweeters and mids no matter what since mids are in doors and tweeters up high. Hard to imagine trying all these options and then having to go back to the original, especially after getting rid of Morel Hybrids as a result of their separation being even worse. If they were down low they probably would have sounded great. Is this an odd scenario? Any other suggestions or am I stuck moving them down so mids & tweets play together and blend and bring fullness out finally? This endless trial and error has been ridiculous I think it's about time I win the battle!

6.5", so if anything they should sound warmer, fuller and richer than both the previous eclipse and morel hybrid ovations which were both 5 1/4 sets... Definately can't make any upper door, dash or A-Pillar locations image and sound smooth & balanced no matter what angling, TA & EQ work I do, just can't tune it in. Also the shape of my cab is very short dashboard with close flat windshield, and doors are very close to you, basically touching. Thus small rectangular shaped front cabin, and think maybe that's why even though usually not ideal location, perhaps in older pathfinders best location may be having tweeters down low with mid but aimed up (even though factory had them in A-pillars), because low down allows most distance from me so they can balance out. Where should I go from here? Never had to spend so much time and money in a vehicle just to get it to sound right :S

Got tweet crossed lower now at 2.5khz & have mid at 3.2khz which seems a little smoother than 2.5, but just doesn't matter, still sounds far inferior to old Eclipses, and those were run passive with only 75rms a side, now I have 150rms to each side with these active, and they just don't blend and get that full sound... This is 5th approach since those eclipses blew up, and I have spent tons of money and heartbreakingly downgraded in sound even though these speakers should be far superior. I loved my eclipses & their tweeters were down beside mid in this vehicle, and the Kaptions I had in my old BMW, with tweets in higher door area were sick (But much better wider cabin, with dash farther away which permitted higher position more I believe)... now these are a better speaker than both those right? But they sound shameful, and so did the Morels... I have done every tweak imaginable... do I need to swallow my pride, accept all my failed attempts at having higher mounted tweets and just move the damn things down so they can blend? And if I go to mounting them low beside mid and aiming up reflecting off bottom of dash like eclipses were, will I be better off hooking rears back up to amp so that I can time align the four corners? Or will I be better just leaving rears running off deck, not having any control of them, and bi-amping fronts off passive x-overs?

Pride has nothing to do with sound. If it sounds better to you with the tweets installed lower, then start there and adjust until you're satisfied. Some vehicles work much better with kick panels than others, and some work well with door positions. There's no set rule, especially in automobiles as they're very challenging environments for sound systems. If it sounds better lower, put them lower.
