ADS HRN-AR-CH3

The ADS / iDatalink Maestro HRN-AR-CH3 (a-CH3) is a vehicle-specific Amplifier Replacement T-Harness engineered to streamline replacing the factory amplifier with an aftermarket amplifier or digital signal processor (DSP) in select Chrysler, Dodge, Jeep, and Fiat vehicles equipped with premium amplified sound systems (such as factory Harman Kardon, Alpine, or premium multi-speaker packages).

Key Features

• Plug-and-Play Amplifier Replacement: Connects directly at the factory amplifier harness location, eliminating the need to cut, splice, or manually run individual speaker wires throughout the vehicle.

• Maestro AR & DSP Integration: Designed to interface factory source units directly with the iDatalink Maestro AR (ADS-MAR), Maestro AR2 (ADS-MAR2), or Rockford Fosgate DSR1 processor.

• Factory Feature Retention: Retains essential OEM features—including fader/balance controls, vehicle alert/warning chimes, navigation voice guidance prompts, hands-free phone integration, and steering wheel audio controls when paired with the companion interface.

• Speaker Output Access: Provides direct access to OEM speaker lines so your aftermarket amplifier can drive the factory speakers through existing vehicle wiring.
