A status offense is the conduct of a child that is illegal only because that child is under age. For example under age, drinking, smoking, and driving, gambling, and going to clubs just to name a few.
Looking at my own Tahoe there are two speakers in each of the front doors. 1 4" round and looks like a 2 " oval. In the rear, there appears to be only one round 8 inch... possibly a subwoofer combo.
