Someones been reading the wrong book.
Frequency cancellation and phase issues are a product of moving the tweeter too far from the mid. That is a proven fact. Running them on a passive crossover (like the one that comes with the component set) Does Nothing to correct that. Reversing the phase on your tweeters may, to an extent, but nowhere near what can be done with a processor.
I have been installing for over 25 years, and competing in SQ competitions for almost as long. I have seen Literally thousands of competition cars, and many, many, many of them with tweeters below dash level. Some of those were world class competitors. Nowhere in the book you speak of does it say to "put the tweeters as close to your ears as possible". It does, however say to find a location as close to equal distance from your ears as possible. It just so happens that the farther you go down the doors, the closer you come to that point. As an example, look at some of the cars that compete in Iasca or Meca 2 seat.(arguably the toughest class to compete in) Alot of those competitors have the mids and the tweets in the kick panels. (as far away from your ears as you can get in a car) These are guys that know a little about imaging and staging.
Secondly, I asked if the OP was overpowering the sub IN RELATION to the mids, not overpowering it altogether. HUGE difference.
Lastly, I myself have taken my 370 to 4 competitions this year. All 4 of those shows were prior to me adding tweeters to my a pillars (which I only did because I DO run a processor, and can cross them extremely high)
My tweeters were directly above the mids in my doors as well.
2 first place finishes, and 2 second place finishes tells me the Judges didn't think it mattered that the tweets were not "as close to my ears as possible"
..............I'm just sayin'.
