Phil is right. "Directional" wire refers to low level signal wire which has
three separate conductors, two for the signal and an external shield which
is only attached to the ground at one end. This end should be attached to
the preamp (or head unit in the case of car stereo). This results in what
is called "star grounding" and minimizes introduction of noise into the
system due to ground loops.
Since audio signals are essentially balanced AC in content, changing the
direction of the wire does not affect the sound. Changing the quality of
the wire (let's not get into that!) or connections (especially!) can change
the sound. A tiny little bit.
