here is my equipment: onkyo tx-sr600 receiver-polk rm6000 sub- polk psw303 - 2 aura bass shakers powered by plate amp. how would i hook all this up if i followed polks suggestions for hooking up my sub? is it ok to run speaker wire from receiver to sub, then the next sub, then to the bass shakers? i think this woud be in parallel? i am not shure how to do it? thanks for any help.
