HAHAHAHAHA.... I didn't have any before pics of my door panels. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gifand he even changed cars and door panels in the process!!
It's not as complicated as your saying. You don't have to "take the guts out" of your door. But you do have to open up the entire door to get in there to add deadening material. Both on the outside and inside sheet metal. The hole does not have to be as big as the speaker. With even just a small wooden ring riser, a 6 1/2" speaker will fit in a hole less than 4" wide. You mount the ring to the door, and the speaker to the ring. Seal the edges with non-hardening clay.well, not quite because I am working with a smaller hole and trying to build it out. I know I will porbably have to take out the guts of my door and cut a hole large enough for the speaker. the problem is after I cut it out I have no way of mounting anything in there.
