Well I have Logitech Z-4 and I want to connect it to my xbox and my TV.I want to be able to hear the two speakers of my TV and the 2 speakers + sub at the same time.So is there some type of cable thats allows 2 RCA cables to 2 RCA[for tv]and extra 1/8"[z4]?Yes I know its not going to be 5.1 or any thing like that But I just think I will enjoy watching tv with more speakers.
