I have a 97 Jetta and have a trunk lid lip mounted K40 modified antenna for 20 meter. Wires run just fine from the trunk, then, if you remove the plastic that protects the sill of the door opening, you can run a sizable wire through them. Then, once at the front of the front door, under that panel is an easy run to the dash. Be very careful lifting the covers off of the door sills, the clips holding them are very secure. I have thought about a screwdriver, but figure the only way I can do it is with a trailer hitch receiver style mount on the back.
