Answer
Well, I would bet that you either blew an amplifier or blew a fuse in an amplifier.  You may have a loose connection on an amplifier as well. It's not too possible for all your speakers to blow in unison like that so the speakers are probably not the problem.  
    Does your system have 2 amplifiers?  One for the subs and one for all the other speakers?  If so check that both amps are turning on, they usually have a light on them somewhere that shows they have power.  Check the fuses if one isn't turning on.  A good install will have fuses under the hood and most amplifiers have fuses on them as well so check for both. (only remove and replace the fuses with the stereo and car turned off!)
    If your system only has an amp for the sub and the door speakers are powered by the dash radio "head unit" then it's possible that the amplifier portion inside the head unit has blown.
    Let me know what you find and good luck!
