    Re: UConnect 8.4 Wiring Info?

    Sorry to resurrect an old thread, but I am about to attempt to intercept the signal between the HU and amp on my 2018 Grand Cherokee Uconnect 8.4 + Alpine and I'm wondering if anyone knows what the difference is between the front and rear signals. It was my understanding that the signal processing and fade are done by the amp and that the signal from HU to amp is full range, full volume, and unprocessed. If this is the case, then are the front and rear signal pairs the same?

    that should be correct yes. So as long as you do external volume you have have two full range outputs from the HU.

    Okay, thanks! I am going to try using an arduino interpret the can signal and control a volume control board, similar to the project you did in your Charger. Nice work by the way.

    Thanks
    an uno and a canbus shield is all you need. the rest just comes from sifting through the signals and isolating what you are looking for.
