Stinger's Optical Interconnects are the purest way to send and receive sound in your car audio system. They improve sonic resolution and reduce jitter, thanks to the pairing of flexible, non-reflective PVC dielectric insulation with a triple-polished, medical-grade, light conductive core. Optical Interconnects are designed to bring out the best in modern ultra-high-performance, high-bandwidth car audio products. They're Hi-Res Audio-ready, they support multi-channel audio, and the flexible jackets allow easy installation even in tight spaces.
