IDatalink,IMaestro AR, Universal Amplifier Replacement ModuleWith Idata Maestro, Ach3 Plug & Play Amplifier Harness For Chrysler, Dodge, Jeep Vehicles For the best sound, replace the factory amp It's an increasingly common problem. You can't replace your vehicle's premium factory radio, but the premium factory amplifier isn't powerful enough for you. Furthermore, the factory amp gets digital information from the vehicle's databus and replacing the amp would mean you'd lose all audio control, like volume and balance, as well as other features like steering wheel controls, audible navigation alerts, warning chimes, and Bluetooth® connection. iDatalink's solution, their Maestro AR module, combines with a vehicle-specific T-harness to supply a clean audio signal plus digital control data to an iDatalink-ready amplifier (like Kenwood's Excelon XR600-6DSP) so you can give your music the premium impact it was missing. How does it work? The T-harness plugs into your factory amp's input wiring, linking the radio to the Maestro module and the amplifier. Your factory radio continues to work just as it always has, but you now have much more power and tone processing ability. It was a common practice, when adding an amplifier or processor to a premium system, to sum the different amplified signals together (tweeter, midrange, woofer), attenuate them down to line level, process them while removing amp noise, and then re-amplify them for the speakers. iDatalink's AR module eliminates all those steps, resulting in a much cleaner output. You get vastly improved sound quality and the ability to upgrade your speakers and subs, while you retain your vehicle's stock radio and all of its functions. Sounds like a win/win to me.Enables the seamless integration of a compatible aftermarket amplifier while retaining the vehicle's factory radio.
