How do you install rear speakers in a 2006 impala?

1. First, remove the rear seat. There are two black lanyards near the base of the bottom cusion, pull them out to unlatch the seat bottom. 2. Remove the rear seat back. There are two small nuts that hold it down, remove them. Remove the seat belt latches. 3. Remove the rear deck. It simply lifts out. 4. Undo the clips on the speaker housings, and gently pry up on the housings. There is a small amount of adhesive which may make you think they are permanently attached; they aren't. 5. You will need a Torx driver to remove the stock speakers from the housing. 6. Installation is the reverse.
