yeah, thats what exactly what im doing, putting sucky $300 6.1 speaker with a awsome sub

,like i said, ill probly upgrade it latter and i dont want the package deal cuz i want big mains later on.
As for now i guess ill have to decide on svs pb12 nds or nds/2.
Should i get the nds/2 $900 or just nds $600 and save some money on better speakers?
Will they have a big differece between those two subs? i like the triple Multiple tuning point on the nds/2, it seems like it will blow the nds out.
MY real question is, i have a rca sub out on the reciever will any of the reciever have rca connection?
Will i be missing anything if i dont use any other connection on the sub?
like the red and black knot, dont know what are they for.
