Not really. I used some of these speakers in my previous car. I based it a little on previous experience, a little on reviews, and the rest on aesthetics. I didn't want it to stick out too far. I aimed them at the headliner with a laser pointer. I'm pretty happy with the results so far, and I haven't played with the time alignment yet. I haven't wrapped the pillars yet, because if I need to make changes I can.
Nope, I didn't get hassled for the windshield, but I did have to strip the front 2 windows.
