Congrats Jay! A nice setup you have now.
As the ICE is freezed for now, let me suggest you some good ideas.
Next upgrade should be the HU and amp. Go for a better Pioneer/Alpine HU. Con some relative of yours' to bring down one for you from PERSIA!
You can find somebody to buy your current amp and get rid of it. Pick up the blau 275 from Jk. Add a 4channel amp like a JBL 60.4 or a Blau 475. Your setup will be complete by then. Remember, who gave you the idea after you go thru all these.
