The amps arent in the doors, they are on the drivers side under the dash. You can see them if you look down there. I can't seem to find the photo of them, but it's out there on the internet somewhere. The 10" (or 8", can't remember) round speakers that are on the door are considered subs. You should be able to see them from outside the door without taking it apart.
