I used a Ron Francis product called "GREY STUFF" part number GS-10 to run the wires through the passenger compartment. It runs under the carpet with the carpet padding on either side of it.

For the wiring into the doors, I used 3/8 steel line which I bent to conform to the bottom door hinge and then flared the ends so as not to cut the wire. I then tack welded the line to the door hinge (it's very easy to burn through the steel line), drilled a hole in the door down by the hinge and then ran the wires from inside the door through the steel line. What is not going to be covered by the door panel will be very hard to see since it is down so low on the back of the door. Hope this gives you some ideas.
