Once it's loose, use your hand, and just pull back until all the clips pop loose. You'll need to play with the door handle in some way (either slip it out of the door panel or undo the metal rods that open the latch, depends on how a civic's built), then once all that's done, pull the panel up so it comes out from where the window goes down, then support the panel and undo the electrical connectors, and there you go. Use the other screwdriver to take out the speaker, then cut the wires (it's probably soldered) then put disconnects on the end of the wire. Put the new one in, and go backward.
