I went to crutchfield, but all they say is the different size speakers that will fit in my car not what is actually in my car. I have a 2004 cavalier ls sport. It is a sedan 4-door. Thanks
4x6s in the front doors and 6x9s in the back window. You can fit bigger in the doors, but you'll have to get or make adaptor plates.
