Sky High Car Audio Premium 4-Channel RCA Cables – 12ft / 18ft / 20ft
Sold by AudioSellerz.com
The Sky High Car Audio Premium 4-Channel RCA Cables are built for serious multi-channel and full-range systems where noise rejection, channel separation, and long-term reliability actually matter. Designed for full-range amplifiers, active front stages, and multi-speaker builds, these RCAs let you run four clean signal channels in one durable, flexible cable.
Each channel pair uses oversized multi-strand oxygen-free copper (OFC) conductors, twisted-pair geometry, and Mylar foil shielding to help fight alternator whine, ground noise, and interference from other wiring in modern vehicles. A heavy braided nylon outer jacket protects the cable from abrasion while still staying flexible enough to snake through amp racks, under seats, or behind panels for clean installs.
To keep everything organized, the four channels are color-coded (Blue / Black / White / Silver) so you can quickly identify front/rear or left/right at a glance. Machined metal, threaded split-tip RCA connectors lock down tighter than standard push-on plugs, helping prevent vibration-related looseness and intermittent connections in high-output systems.
If you’re wiring an active front stage, multi-channel amp, or processor-based system and want pro-grade OFC 4-channel RCAs, this is the premium option from Sky High—now available through AudioSellerz.com.
