Polk PSW12 12" Subwoofer not working

System: Onkyo TX-DS575X Receiver, Vienna Acoustics wall-mounted speakers with PSW12 12" Subwoofer.

Recently upgraded my TV to Samsung LCD. When the company that I bought the TV from hooked the system back up, everything worked fantastic.

However, I had to purchase a new entertainment cabinet to support the new TV. When the cabinet came, I unhooked everything, put it back to how I thought it was hooked up and now I only get sound through the Vienna Acoustics and barley anything out of the sub-woofer.

There are only so many connections that can be used. The connection I used is the unfiltered, single cable from the sub-woofer to the receiver. Any other connections I set up, I get no sound at all. And with the sub-woofer pre out set up, I only get minimal sound and the volume control does not control the subwoofer volume as it did before.

Any ideas?

Thanks in advance!
