I have the pioneer system thats stock with cblts, but everytime i play music, and its only some songs, a horrible buzz comes from the driver side speaker, the small one near the window. Now some songs i can crank up loud and i dont hear anything, but other songs i can barely put the volume up and i hear that stupid buzz. is it blown? or is something just loose?

 

probably blown. something "mechanical" so it still plays but at that certain feq you can here ____ that was disconnected/broken
