hooking up subwoofer to reciever - cable problem ?

[pmontagne]

I purchased an Onkyo TX-SR504(B) AV Receiver and a Polkaudio RM6750 audio system from Circuit City. Hooking up the system and ran into a snag; The reciever has a pre out for the sub woofer which is a single connection and the subwoofer has a line in which is a double connection. What kind of cable do I need for this hook up?

Thanks for any help,
Pat:confused:

Read the directions. It will tell you which jack you need for mono ie. left or right.

Use a Y connector to feed both inputs on the sub so it will give you a 3 db boost.
