How to remove door trim?

I've got a 2002 coupe, By now I know there are screws behind the SRS badge and the door handel.
I've removed the one behind the SRS badge.. but got now idea how to access the second screw.
can anyone help?
Also... how can I remove the speakers?
there is a black box in the trunk, it has a cable... I remember this box leads to the dashboard. right?
so while i'm working on the car, i want to wire it for a new sound system. what kind of cabels should I use for future sound mods?
thanks a lot.
