99 prism door panels

ok, so maybe it's simple, and im just a moron.
but how do the interior door panels come off of a 99 chevy prism?
i am installing new speakers; I got the back ones in no problem, figured out the rear deck in no time. but i have no clue how the driver and pass. door panels come off, and i dont want to just dig in, and end up breakin something. thanks for the help
