Cheers,
First thing i would do is identify, and mark all the wires comming out of the radio, to the wiring harness.
ie
power
remote
front speakers
rears speakers
and any other alternate wires.
may take a few minutes, and even some google for the wiring diagram(if not marked)
then trace every wire. The problem with most speaker rewiring jobs is people get lazy, or have no idea what they are doing, this is a good time to correct this. it may be a pain, but there is no easy way to do it.
also they may have crossed wires, cut wires, or lack of wires.
as a note you should not have to wire the doors if they currently exsist, just trace the path until the meat up the the wire you have identified in the wiring harness.
a very easy way to do this is with a electronic mulit-meter(10-20 dollars at radio shack or autostore), set it to ohms, and using a long piece of wire conect one end to the unknown wire, and use the probe of the other connecter to test each wire in the wiring harness. the display should be around 0 ohms, or very very low. it you see a value like xxx Kohms, or Mohms, then you are not on the right wire.
some testers have a buzzer under ohms for "continuety"
