Sorry to post this here but it won't let me post in the thread. I'm trying to add a kicker hideaway to my 2018 6 GT and using the diagram you posted, I tapped into the front inputs on connector 322A. I used the same type of splice clip that the OP used and my stock equipment seems to be functioning normally after the splice. The subwoofer however is not getting any signal from the speaker wires. I'm sure they were placed to the correct wires on your diagram, left to left, pos to pos, etc but were those the wrong wires to tap to begin with? I don't want to just keep cutting into the harness if I don't have to. The sub is getting power and turning on and the ground is good according to my multi-meter.
