Thanks Sonnie, I do have it in couple mode but I only get output from which ever input I have connected. I have one cable from my amp and each of the two subs have an individual cable left and right channel. I assumed that couple mode would mean that 1 input should provide the same signal to both channels. This isn't happening and no matter how I configure it won't provide the signal to both outputs. If I plug right output I get right sub working and vice versa for the left. I have couple mode working as both lights are on. Is there something wrong with the unit or am I thinking wrongly here?

Cheers.
