At the top of the kick panel there is a little grommet that the wiring for the door dome light switches runs through. Push the speaker wire through that from under the dash and keep feeding it until you can see it in the kick panel. Then you can feed it into the door using by following the outside of the door hinge arm. Snake it into the little gap and finish feeding to where your speaker is installed. Secure on door hinge arm with a zip tie.
I would post pictures but my truck is a bare shell at the moment.
