'92 Pickup - Removing Door Panels?

Hey guys,

I'm trying to rewire the speakers that were installed a few years ago in my door panels (custom holes were cut). Problem is, I'm not exactly sure how to remove these panels, and I don't want to break anything. I know there are snaps all around the edge, but is there anything I have to do first? If anybody can explain this to me, or direct me to a guide/example, it'd be appreciated.

Thanks
