Removing seats & speaker replacement on the 308 GTSi

I intend to refurbish the seats with Leatherique restoration products. It appears the best way to do this is to remove the seats and bring them inside where it is warm. I also want to replace the speakers in the doors. Is removal of the seats and pulling out the lower part of the door panel where the speakers are a big job?

 

Actually, pretty easy. The seats are held in by four 6mm allen bolts each and can be accessed by sliding the seat back and forth. Nuts are captured under the car (ouch) so just unscrew the bolts from the top side. The door panels come off easily by removing the philips screws around the perimeter. Speaker comes with the door panel.
