REPAIR PROCEDURE

1. Remove the rear seat bottom and seat-back.





2. Remove the three amplifier box mounting bolts. Disconnect the three harness connectors, then remove the box from the vehicle.





3. Remove the 10 mounting screws from the cover of the amplifier box. Remove the cover. These screws have a 1/4" hex head. If you have only metric wrenches, use the handle of a removable-blade screwdriver. This should have a 1/4" hex.





4. Remove the mounting screw(s) from the I/O printed circuit board. The type B board has one mounting screw, and the type A board has four mounting screws.

6. Make sure the amplifier box is facing as shown. Each replacement sub-amplifier has a white dot or a black dot to show if it is for the front or the rear speakers. Install the sub-amplifiers with a white dot on the left side of the box. Install the sub-amplifiers with a black dot on the right side.

7. Mount the sub-amplifiers with the original screws. Reconnect the electrical connectors.

8. Reinstall the I/O printed circuit board. If it is a type A board, make sure you have the isolation washers in the proper locations.
