hi, the new svs should arrive tomorrow :)

i just have one quick question, i have the RM6900 system w/ onkyo tx-sr503
and from the RM6900 manual they recommend that i use the front speakers wire to connect to the sub instead of the preout subwoofer connection.

now with the svs Pb12isd do i have to do the samething or most of you guys connect the sub with receiver through the 'Preout subwoofer' cable?
