Another thing: my installer had to cut the original (door) speakers to remove the mounting brackets (I did not see what was removed, but I do have one of the OEM speakers). The removed mounting brackets were used to mount the new speakers. So others may need to do this as well or perhaps there are after market brackets that places like Crutchfield sells to the self-installers.
Methinks something is very wrong with that. I replaced all 4 doors myself and there is ZERO reason to damage anything. There is a simple plastic ring that uses two plastic points and a screw to secure to the door, and the speakers screw to that. Unscrew speakers from bracket and then unscrew the single screw to remove bracket. To install any new speaker, there is a simple replacement plastic spacer ring that costs 10 dollars per pair, made by Metra and fits multiple Hondas. Anything from components to coax can fit depending on mounting depth. The back of the door panel grill must be trimmed for really tall speakers and you could probably use a wider spacer ring for deeper mounting depth.
