This cable is also used for audio applications. The description is "HITACHI P&A OFC INTERCONNECTING CABLE FOR CAR AUDIO." Set includes: 80cm x 2 2m x 1 The continuity has been confirmed. Because these are thick oxygen-free copper (OFC) cables, the sound quality should be about two ranks higher than commercially available thin red and white cables. I have cleaned them lightly, but some stickiness remains due to aging. Bids are welcome from those who don't mind this.
