No RCAs, but there is a DIY guide out there somewhere that shows how you can pull apart the amp and solder some in...
It's an interesting system when you start to read up on it - IIRC the headunit and amp act more like one system rather than a headunit sending straight sound signals to the amp it has some other data going back and forth... Anyway, search these forums, it's probably here, failing that you ought to be able to pick it up though Google.
