I have only 1 RCA 'out' jack on my TV- i used two of these Y splitters to duplicate this jack and run one of them to my wireless speakers to listen to my Direct TV Sirius radio stations on the deck. it worked great. I just wish they made some of these particular typese of Y cables in this short length for a little less. But the price was not that outrageous as it's still cheaper than most places, and the length was perfect. I hooked up a 3.5MM jack to one pair and it's still hidden behind the TV.
