The Stinger SI4212 12-foot 2-Channel 4000 Series RCA interconnect cable is engineered for high-end car audio systems and uses precision-twisted oxygen-free copper conductors with a multi-layer foil and braid shield to minimize EMI and RFI and maintain left and right channel clarity.

Each 4000 Series cable is terminated with gold-plated precision-machined RCA connectors and encased in a flexible abrasion-resistant PVC jacket. Designed for linking head units, processors, and amplifiers, the SI4212 benefits from professional installation for optimal routing and secure connections and pairs with Stinger’s ground enhancements and remote turn-on leads for complete system upgrades.
