I wasn't aware there was a question about hooking the amp up to the door speakers.so has anyone actually answered the question about hooking up the amp to the door speakers? if not, you can run the speaker wire from your amp over to the door jam and throught the hole that all teh other wires go through from the door to the interior, or you can run the wires up behind the new deck and wire them to the aftermarket harness that has the speaker locations you are looking for(not the wires going to the deck but out to the speakers)
