Hey all, I recently purchased this tv:
http/www.costco.com/LG-47%22-Class-1080p-120Hz-Smart-LED-HDTV-47LB6100.product.100106877.html?catalogId=10701&keyword=47lb6100&langId=-1&storeId=10301&refine=
My Bose speakers are RCA, I want to use the Bose speakers as the primary source of sound for my TV. The only audio output on the TV is Optical Audio. I need an adapter from the RCA to the Optical. I can't seem to find out what I need. Please send me a link of which adapter I need to buy. Thanks!

What speakers are they. Just because they have rca doesn't mean they are powered
