I used the rocketfish wireless subwoofer kit. on the back of your amplifier there should be a subwoofer out plug. you plug that into the back of the wireless reciever unit., and then you plug the other unit into the back of your subwoofer somewhere within about 75 feet of the reciever. turn on the subwoofer, then power up your amplifier. then turn on the two wireless pieces, I plugged mine into the reciever on the backside so when the reciever in on so will be signal sending piece.
Not sure if your wireless subwoofer will work with your amplifier or not. It looks like it is designed to work with a sound bar.
