Nu4-6000 bridged not producing sound.

Hello,

I have a nu4-6000 amp and have 2-um18 and 2-um15 subs. I started by taking one of the um15 out of the box and wiring it in series. I wired my 4 pole speakon to 1+ and 2+. Set the mode for a/b to bridge and the crossover to LF. The guy I bought the amps from had 1/4in TRS Stereo Plug to RCA jack adapters on the inputs. I have my lfe cable plugged into input A. I get no output when I run test tones from my receiver. Any ideas? Something I'm doing wrong?

Thanks,
Dalton

Have you tried playing from each channel in straight mono (not bridged) to make sure all channels/inputs/outputs are working as expected?

I hooked up the other nu4-6000 and and both sets of bridged channels worked on it. I will try mono through a and b. Also, would I need to change the neutrik connection to 1+ and 1-?

I also ordered xlr to rca cable to see if that helps. Maybe it's something to do with the combo xlr/1/4" trs connection on the inuke.
