Hi guys, I have searched endlessly to solve this issue, I have checked all the fuses and have unplugged components under the rear seat to reset them with no success. I have a fibre optic feedback loop to help with diagnosis.

In the image bellow, I have a optic signal to the plug in the yellow box, leading me to believe that the command unit is ok...however I have no signal to the plug in the red box. Does that mean I have to look upstream of this component to find the problem? If thats the case can anyone tell me which component to look at and where it is? I was going to check the amp under the drivers seat but wanted to see if anyone could provide insight before removing the drivers seat or cutting up the carpet.....



Any help would be much appreciated, This is a really frustrating problem to have.
