All you have to do is remove the mounts/clips on the factory mounts for the infinity 6x9 (they sound great) I had the problem of having to splice in 6" of speaker wire for the differant connections. but other than that easy install.
The door on the other hand was a little bit more difficult. I went with PG 5.25" comp so i had to get mounting brackets. The fun part will be removing the factory tweeter and gluing the new one in place, some recommend hot glue, i used crazy glue works great.
Best part opening door panel and finding $20 in your new car?!!
