hello everyone. Does anyone here change the speaker?? How hard to do it?

Can anyone give me some advice how to take off the door panel?? I don't want break anything, PLZ!!!

I'm planning to get Pioneer TSA1682R, does anyone instill this in the Fit???

remove the screw behind the door handle
pull on bottom of door panel and pop out clips
this will pop the trim on the arm rest loose, and pull that off
there are like 7 screws behind that that hold on the arm rest and the clip for the wiring for the window and lock

after that, lift up and it'll slide off
