Subwoofer wiring for Audessy EQ, advice needed


Hello all,
I have a Marantz Av 8003 and a JL Audio fathom F110.
I currently have the SW connected to my AVP via a Wireworld oasis xlr connector. If I get another Subwoofer Should I a Y interconnect or a single xlr and run it slave mode. How would either scenario effect the use of the EQ?
