Issue with factory integration.

Edit: I will be using the outputs of the Sony amp for the inputs of the FiX. Hey friends. I am in need of some assistance. I am retaining my factory Sony/Sync headunit. I need to use a Audio Control LC7i or JL Audio Fix to get the low level to my aftermarket amps. I have a factory Sony amp and don't know what the input wires are coming from the headunit. I know what the speaker outputs are but not the inputs. In the photo the twisted pairs are the outputs. Could it use a digital signal from the headunit to the amp? If so then what do you do?

Thanks in advance for your help.
