XLR cables provide absolutely no advantage for you if your receiver doesn't have an xlr connection. You would have to get an XLR cable with an RCA adapter, which defeats the purpose of having a balanced cable (there's no 3rd connection to reduce noise).
Your receiver only has one sub out connection, the other sub connection is for multi-channel input so no Y cable is necessary, unless you are running multiple subs. Y'ing two receiver sub out connections to a single sub is unnecessary anyway.
Thanks i wil definitly go with RCA but the ultralins say they are balancedSUBSONIX® POWERED
