Sigma Studio issue or is it just me?

I am working on the KABD-4100, its a 3-way setup and I have not been able to get the bridging part to to work. I can get the mid/tweeter to work on J13 fine, but J14 is not outputting anything at all. I have 2 different boards, I have tried both of them. I have tried swapping cables and I have tried the default setup in the demo pack, that doesn't even work!

I read zero coming from the board on the DAC2 output. I am listening to the other ports as I am typing this. I am assuming this is correct? If not what am I missing, if there is any physical things I can do to troubleshoot I'm all eyes! Crossover is at 100hz for the Lo. Oh, I also have the bridging connectors connected, in fact the ONLY sound I have heard is when I connected them and they charged and discharged until it was seated. I also tried unbridging and using the outputs, that didn't seem to work either, though I didn't unsplit the wiring to the sub.
