i'd have to say that the most difficult part of the installation is removing the
OEM speakers from their housings. a bit of effort is required to do this. enough
effort that u feel as if ur gonna break something from using so much force.

also, when removing the front door panels, be extremely careful not to pull the
panel off at any awkward angles. if u have lighted door handles, the piece attached
to those breaks quite easily and costs about $60 to replace. trust me on this
one. as for the rear door panels, i keep saying this until i am blue in the face,
they do not need to be removed. when i did the install on my previous 4.6is,
i did not remove the rear door panels.
