Because if it is like mine, the door speakers were not opted from the factory. It only has dash speakers and rear speakers. The factory molded speaker brackets were not there, nor were the wires. This sucks. I will have to either rig it up, which will probably screw up the sound of them, or go to a junkyard and pull some brackets from a wreck. That still does not solve the problem with running the wires, which is quite difficult because of the factory door boot has a connector for door removal and ease of installation, maybe the wires made it up to that connector.
Good luck installing,
