how to run low voltage wires for under cabinet lighting
Not sure your exact configuration but I wouldn't bother with sheathing. It just makes the wire more visible and objectionable. I would run as much wire under the cabinets tacked behind the cabinet faces so its not visible. I would then drill and run inside cabinet, again behind cabinet face in a front corner, to top of cabinet, drill another hole through top of cabinet and then behind the cornice or crown molding across to range and then back down.
