If you mean the rear shelf removal, then you begin by removing the rear seat (lift to release the corner clips on each side holding the cushion to the floor). Then remove the fasteners for the seat belts, then lift the seat back to raise and release it from its clips, and remove it from the vehicle. There are then a lower and upper trim panel around the back shelf that you need to remove (these may be on each side of the shelf, e.g. they are called 'quarter trim' panels). Then you will see some push-pin fasteners that hold the shelf across the front lower edge, so you gently pry out the center push-pin of each one of those to release the fastener. Then you pull the shelf forward to release it from the clips that hold it under the window. Then remove the wire to the center high-mounted brake light. The panel with its speakers attached can then be removed, but also remove the wires from the speakers so you don't break those. connections.
That is the procedure as shown in my '98 manual.
