What wires out are you using, and do you get any sounds with other speakers hooked up? Make sure the optical connection is working properly first.

The transducers would normally connect to an external amp that is connected to the line level sub out on the receiver.
If your "receiver" came from a HTS is might have a speaker level subwoofer output but that still should be used with a passive subwoofer. The transducers are meant to augment a sub not replace it and you might not be able to power them with the same amp as the sub.

Sorry, but you're guessing and you're wrong. As they say, RTM.

It requires an AMP to power it, 50WATTS RMS @ 4 OHMS.

They are not powered in anyway, and thus need an amplified signal and not a line level, but a powered signal.
