Amp wire in 2003 Ford Ranger

It sounds like you have one without carpet- just the rugged black liner.  If you want, you can run power underneath the truck, and come in through the floor board (use a grommet) back where your amp(s) is/are.  Put split loom around the wire and ensure it's good and secure.  As far as RCA's, remote and speaker wire, see if you can go up the a-pillar and above the headliner, behind paneling in the back, or wherever, to your amp(s).My ex once told me I have a perfect face for radio.

Yes it is the rugged black liner but i have already figured a way to get it in.  But thanks
