Hi, My little ECHO have no door speakers in the first place. Does any know how to install one? Please tell me what do I need if im doing that myself. e.g Tools, how to take off the door panel. And also what size can I go up to with the speakers? I also hear some issues with speakers that are too deep for the door, is that ture? PS: My car is the 3doors hatch Australian spec 1.3L Thanks
