No, ACM is the radio module in the center console that includes the CD player (not the screen part!).I have the premium without subwoofer, do I still have that flat variable line? ACM is the factory amp correct? I live in Canada so I’d say yes I have the American model.
Any diagram or how can I find this line for my subwoofer?
Thanks for you input, really appreciate that.
The amp is located in the drivers kickpanel.
They are connected with 4 signal wire pairs front/rear left and right and CAN bus wires.
The signal from the ACM to the stock amplifier is fullrange variable line output without equalization as far as i know.
In a premium system the factory EQ is applied in the amplifier, not the ACM. In base models without stock amplifier it is applied in the ACM.
So by integrating in between the ACM and the stock amplifier with the help of a T-harness you get the best possible signal you can have and use this for a subwoofer.
So i always recommend that instead of buying a line output converter in case you have a premium system.
If you wanted to replace the entire stock amplifier i would recommend the idatalink HRN-AR-FO3 harness to replace the stock amplifier, but if you only want a subwoofer a T-harness behind the ACM is the way to go.
