I have these running from my Kenwood KDC-X997 head unit to my MTX 4300x amp (from 1999) mounted on the right rear seat back of my '02 Explorer Sport. Sounds good and no noise issues. The connectors hold pretty tight and the cable is flexible. It's flat and doesn't have a plastic blob tying all the cables together, making it good for running under the amp and not having too much excess cable sticking out.
