Alright so im running stock bose deck,stock bose speakers in the rear (6x9) a 12" alpine sub and amp. My passenger door speaker is rattling alittle now. Pisses me off when I have a luxury car with rattles. If i wanted rattles i would of kept my sunfire. Do you guys think my speaker is blown,loose,anything? What make are those speakers, Ive heard they are panasonic. Thanks for the help.

 

If you have the stock bose system, then they are bose speakers, if they are rattling, you can check the speaker grills first, but most likely the cones of the speakers are blown. The bose speakers have crappy paper cones and are known for blowing, that's why I call them blose speakers, check around the center of the cone and see if there are any cracks or holes around the dust cap in the center of the cone or the outer surround

 

Oh ok thanks for the help! I cant stand rattles.
