Audio Systems: Car speakers, repair question, car speakers

Question
Hi...I don't think this a repair question because I have no clue about fixing speakers...I just want to know if it is possible to blow all the speakers in a car, left, right, front and back? They were working fine one day, then the next no noise at all except a "puff" noise when I turn the radio on.  

Answer
If the stereo does make a very large "puff" I guess it is possible but very unlikely.  Its more likely that the amplifier blew out.  let me know more about your system if it's after market or factory or a mix.  also let me know what year make model vehicle.
I can help you test the speakers very easily.
