2 questions:

Any suggestions on the alignment of the car? I've taken the car in to the dealership to get the alignment done once already because it was pulling to the right on the interstate. Now the car pulls to the left and sometimes to the right. So maybe the over compensated? Any suggestions on certain numbers to get the wheel in? (Roads are fairly smooth in north florida and i haven't hit anything/curbs)

And second when I first bought the car (last June) one of the speakers in the front passenger door was blown so the dealership replaced it, as of recently the speaker is blown/rattling again same door and the rear passenger speaker is also doing the same thing. Will i have any trouble getting this replaced again under warranty?
