Feel for you man. Happened to my dad's Camry everything was taken deck, amp, box and they even tried to jack the car but all they did was mess up the lock by throwing a screwdriver into it.
I want to add a sweet stereo with a custome lcd/comp combo but I work in a bad area (live in a good area oddly enough) and really don't want to risk it.
Did they do any damage to the car itself??
