I am having trouble figuring out how to take the seats out so i can install my subs. i have a 99 4dr civic. I cant figure out how to take the rear seats out so i can run the cables throug there. any information would help

 

Not sure about the 4dr... but the 2 dr, you first have to fold the seats down. Next you have to unbolt the back front the hinges (3-4 bolts). Then there should only be a bolt of two holding the seat bottom in from the back. The front is just supported by clips.
