i own a 1996 cavalier, i installed a aftermarket stereo into it, the wiring is all hooked up right, and ive been having issues with my speakers. my fronts dont last longer then a week or a month. have to push on the cones to make them work sometimes and the speakers have always been brand new. i replaced my rear as well and i have one that works and one that doesnt now. brand new speakers were put in and they both worked when the stocks were in them. any suggestions? i can use some help im getting sick of buying new speakers if that isnt the issue.
