Key features

Utilizes balanced twisted-pair core wiring to natively reject RFI (Radio Frequency Interference) and EMI (Electromagnetic Interference), maintaining a completely noise-free audio path. Oxygen-Free Copper (OFC): Constructed with high-purity OFC copper conductors to prevent oxidation, lower electrical resistance, and deliver uncompromised musical clarity. Platinum-Plated Terminal Tips: Outfitted with heavy-duty platinum-plated female RCA barrels to resist cabin moisture and maximize signal conductivity. Direct Amplifier Compatibility: Perfect for modern amplifiers equipped with auto-sensing, high-level compatible RCA inputs (like Rockford Fosgate’s Punch and Power series amps).
