Looking to add a JL stealthbox

[NUTSHEMI]

I am looking into getting a JL audio stealthbox, besides amp and wiring what else do I need to hook it up. I have read something about a line out converter. What is it and were does it go? Also what is a good one to get? I have the RBZ head unit with the alpine system. Thanks for any help guys.
