Audio Systems: trouble getting to the 6x9s in my car, chrysler concorde, 2002 chrysler concorde

Question
I have a 2002 chrysler concorde and I would like to replace the factory 6x9's w/ better ones but I cant figure out how to access them from the rear deck. I looked around quite a bit and discovered that the tops of the screws are facing up, which means the speakers must be installed from the top of the rear deck inside the car (as opposed to being installed from the bottom in the trunk). How do I go about getting at these speakers? What do I have to remove? Thank you.

Answer
you have to remove the bottom seat first two clips in the midle
then you have to remove the  back part of the seat  you will need some tools for that
and then you remove the rear deck they are only clips
if your vehicle comes with the infinity sound system you can only use original speakers or midbass speakers nothing else will sound good
good luck
