I have a 98 civic h/b and thinking of upgrading my sounds in my car. The car is a CX model with the factory radio. I know that the car has only the front door speakers because I turned the radio to fade to the rear and I couldn' t hear anything. I just want to know where all the possible factory locations for speakers are in the car???Also, whats the difference between front door and side panel...this came up when I was on crutchfield.
