Sounds like someone needs to go klipsch Pro in a hurry..... Don't blow your nice "home speakers" that aren't made for what you want. Go buy some KI 362 IIs or KI 396 IIs from @MetropolisLakeOutfitters and try your subs with em (you will very likely need a better sub (s). You may not have enough drive on output of receiver to input of amps. Don't worry about the number. If the amps aren't clipping, it's not a problem. Now, the question is, can your speakers handle the abuse you are giving them....?
