I have an original Surround Bar speaker with a Polk subwoofer. I recently moved and can no longer run wires for the rear speakers due to wife issues. Will the Rocketfish RF-WHTIB Universal Wireless Rear Speaker Kit work with the Surround Bar? Would I plug the Rocketfish sender unit into the rear speaker jacks on the Surround Bar and then aim the sender unit at the Rocketfish Receiver unit connected to my rear speakers? I am running my Surround Bar with an Onkyo TX SR-705. Thanks for your help.
