Eliminate audio feedback and unlock your system's true potential. When upgrading your car audio with an aftermarket amplifier or subwoofers, your vehicle's factory Active Noise Cancellation (ANC) system can cause severe interference. Instead of canceling road noise, it creates harsh feedback, drone sounds, or inconsistent bass. The iDatalink Maestro ACC-ANC-CH3 bypass harness solves this problem by safely routing audio signals past the ANC module, ensuring your upgraded sound system performs exactly as it should. | Maestro | | Active Noise Cancellation (ANC) Bypass Harness for Select Chrysler and RAM Vehicles | Black | Best Buy
