SHCA Premium 4-Channel RCA 12ft-20ft

Sky High Car Audio Premium 4-Channel RCA Cables

Pro-Grade OFC RCAs for Full-Range and Multi-Channel Systems

The Sky High Car Audio Premium 4-Channel RCA Cables are designed for full-range amplifiers, active front stages, and multi-speaker systems where channel separation and noise rejection are essential.

Built with oversized multi-strand OFC conductors across all four channels, these RCAs utilize twisted-pair geometry and Mylar foil shielding to reduce interference in complex vehicle environments. The heavy braided nylon jacket protects against abrasion while maintaining flexibility for tight routing.

Color-coded channels allow for quick and accurate installation, while machined, threaded split-tip RCA connectors provide a secure, vibration-resistant connection at the amplifier or processor.
