The proper location for the wires you are running is through the factory plastic channels under the front seats. As ashman has said seperate the rcas and the power wires by at least a foot. I always run all wiring throught these channels because other wise the only location is along the thresholds and this always causes the carpeting to bulge and not fit right anymore. Good luck
