$1K for everything is not enough for the equipment you're looking at. Those components and the 8500BHS already put you at $750 or more, assuming you find a great deal on the head unit, probably a used one. Plus CES is coming soon and there's always new stuff announced then, unless you don't want to wait another 6+ months potentially for a high end DVD head unit to come out.
Did you really say you want subs in the doors in a huge SUV? I don't want to misunderstand that part.
