I want to use Logitech Z323 subwoofer with my Yamaha receiver

[guydani]

I would like to use Logitech Z323 subwoofer in my living room, i have Yamaha 565 receiver, and i want to use only the subwoofer without the speakers. I tried in several ways to do so but i didnt succeed. If someone can please help me and explain it to me I would be great.

in my receiver there is a regular RCA subwoofer output
and in the sub there are to RCA inputs (Red & White)

Thanks Guy

Does your back of the sub look like this?

Can you just use the subwoofer output on the reciever and plug it into the Auxilary Input on the subwoofer? You could probably pick up a cheap RCA Y-Cable to adapt the single sub out on the reciever to the 2 inputs on the sub.
