No they don't usually hit because of the quarter vents. This means you have more clearance in the door where the door glass runs down. I got away without using door pods or anything.
I bought a high quality set of 6's and I'm still surprised at the bass they put out. It all sounds nice and crisp and clear.

Make sure you spend a bit of time sound deadening the inside of the door and stop all the rattles etc inside the door before the door trims go back on - you can learn from my mistake cause I didn't think they would be that loud
Anyway I'll get around to it one day..........along with everything else.
