I am having troubles getting a subwoofer signal out of my eclipse cd5435 to my amp. I managed to get the amp to turn on, and i have the rc cables hooked to the non fader line out. But still the subs refuse to turn on... i believe this is because i'm missing something on the cd player as to turning on the signal maybe? like a subwoofer turn on or some programming that would allow the signal to be sent out
