Are you sure the rca output is for directly driving a sub as opposed to
connecting to an amp/powered sub?
I think this is line level. Try the connection and find out. A balanced line
receiver may work or even better, using a balanced conversion on both
ends. If you use a small amp and as I suggested to another post, using a small
Radio Shack isolation transformer to feed the subwoofer RCA input, will also
work without producing any hum from stray fields or ground loops.
