Retain your vehicle's factory features with a new radio

You want to install a new car stereo in your Chrysler, Jeep, or Dodge, but you don't want to lose the useful features built into your factory radio. The Axxess AX-ADCH02 harness works directly with the AX-ADBOX1 or AX-ADBOX2 interfaces to give you the ability to connect your new radio to the existing wiring in your vehicle. The harness will also keep your safety warning chimes, Retained Accessory Power (RAP), and the blind spot detection system if it's present in your vehicle.

Important Installation Notes: You must use this harness with the AX-ADBOX1 or AX-ADBOX2 interfaces to install your car stereo.

Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if the AX-ADCH02 and its accompanying interface are compatible with your vehicle. Warranty: 1 year.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.

Factory Amplified/Non-Amplified Compatible: The Axxess AX-ADCH-02 can be used in vehicles with or without factory amplifiers, including digital amplified systems found in many Chrysler/Dodge/Jeep vehicles. Both balance & fade control are retained when used with AX-ADBOX1 interface (sold separately). The AX-ADBOX2 interface (sold separately) does not retain fader in vehicle's with factory digital amplifier.

R.A.P (Retained Accessory Power): The ignition power source of many vehicles keeps the radio on until one of the doors is opened. This feature is called the R.A.P. (retained accessory power).
