Crossover design is a science that is used in DIY world of car and home audio. Some people think its a bandaid solution and it is if you use inferior quality speakers ie "BOSE" but it does work!
I have been doing DIY for 15 years and I have developed my own custom software for crossover and enclosure design. If anyone is interested in it I might even share it.

Im curious how your changing the phase in your passive crossovers. The phase you can control through the crossover is electrical by utilizing different crossover slopes. You said you were using the focal passives so Im lost there.
Also phase as you refer to it being affected by the vehicles acoustics is not controlled through the crossover but rather through the install, aiming, and level matching primarily. Im also curious how you're utilizing time alignment with a passive network. You would only be able to adjust the stage left and right. Time and Frequency of a driver are two different functions, correct me if Im wrong. Also if you are using a passive filter time alignment wont help with height of your tweeter and the only way you can change phase without moving the tweet is to adjust the slope, affecting the electrical phase.
Again please dont take my comments the wrong way. I hope Im not out of my league because I'd like to think we can have an intelligent discussion. Id be curious about the program you made for crossover design. It could be a nice tool to add to my collection.
