I connected the transmitter unit to the receiver and the receiver unit to the subwoofer. Had them flipped the first time as they look almost the same but are marked TX and RX. They connected automatically so I didn't have to connect them as per the instructions. Turned on the music and was very impressed with the sound. So I have great bass that I've been enjoying for a long time, but no cables are visible in my home theater room. I recommend this product.
