We have an old Isuzu that has oddball speakers, we asked for an installation that would allow us to use the original grills. They end up doing some really nice costume carpeting work to fill the speaker holes and use the Kenwood grills. They did a great job, my wife was happy and the sound is very good. It turned out to be a very nice Christmas present for her. And all of the old brackets are and covers are saved so they didn't tear up the door panels. Given all the options I think the guys took the best route and the were willing to pull everything out if we didn't like the result.
