I replaced all the door speakers last Winter with some I chose from crutchfield.com. They may be a little more expensive than some other resellers, but their installation directions are good, so it's worth it for me.
I went with these 6x9 in the front: crutchfield.com/p_2064CS6934/Kicker-40CS6934.html?tp=105&avf=Y and these 6 1/2" in the rear door: crutchfield.com/p_2064CS654/Kicker-40CS654.html?tp=105&avf=Y. I didn't replace the door or dash tweeters, and I'm happy with my choice to leave those be.
As far as figment goes, I definitely recall one of the two sets not quite going in as easy as I might like. I believe it was the rears, and the issue was that the mounting holes didn't line up between the door and speakers. I just used some self-tapping screws and it was fine.
Also, if memory serves, even though they were from crutchfield, I still think I had to clip off the existing speaker harness and splice the wires.. Overall, it took me a few hours (2-3 iirc), mostly because I always go slowly with door trim.
