I recently bought a Sony Bravia DAV-HDX585 Home Theater System and Television. I enjoy it - for my imperfect ears it seems like good value and I like the way the AV system and TV work together. But there's a problem. I have speakers on my deck from my old receiver and would love to hook them up to the Sony AV but the tech tells me it can't be done. He says there are outputs for the 5 speakers that come with the system but no other audio outputs. Is there any type of speaker jack splitter or switch that I can purchase to allow me to hook up these two other speakers to the system? I apologize if this question has been asked before. I did spend a couple of hours searching but may have not understood all the technical specs (I'm a computer geek, not an audiophile).
