REMOVAL & INSTALLATION



Front
INSTRUMENT PANEL MOUNTED

See Figure 1

Most early model trucks were equipped with instrument panel (dash) mounted speakers.

  1. Disconnect the negative battery cable
  2.  
  3. Remove the front speaker grille screws, then lift and remove the grille.
  4.  

On most earlier models, the grille screws retained the speaker as well. But, always check to make sure no additional fasteners were hidden under the grilles.

  1. If equipped, remove the speaker-to-instrument panel screws,
  2.  
  3. Lift the speaker and disengage the electrical connection(s), then remove the speaker from the vehicle.
  4.  
  5. Installation is the reverse of the removal. Make sure the speaker wiring is properly connected before attempting to test the radio.
  6.  

DOOR MOUNTED

Some later model trucks (or early model trucks with aftermarket sound systems) may be equipped with door mounted radio speakers. Access to factory mounted speakers on late model vehicles usually requires removal of inner door trim panel. Aftermarket speakers may be mounted in a variety of ways, but will often not require trim panel removal. In order to save time, be sure removal of the panel is necessary before starting. If the grille fasteners are accessible with the trim panel installed, then panel removal may not be necessary.

  1. Disconnect the negative battery cable
  2.  
  3. For late-model vehicles, remove the door trim panel. On early model vehicles, check for any accessible fasteners on the speaker grille. If the grille can be removed, do that first to see if the speaker may be removed without removing the trim panel. For details on door trim panel removal, please refer to the procedures in Body of this guide.
  4.  
  5. Drill out the heads of the old speaker retaining rivets. Again, aftermarket systems may not contain rivets. If equipped with screws, unthread and remove them.
  6.  
  7. Pull the speaker from the door and disengage the electrical connectors, then remove the speaker from the vehicle.
  8.  
  9. Installation is the reverse of removal. If the speaker was retained with rivets, use new ones to fasten it to the door.
  10.  

Rear

  1. Disconnect the negative battery cable
  2.  
  3. Remove the necessary trim panel for access to the speaker. Lower trim (most regulator cab) or the upper trim panel (extended cab).

  5. Disengage the necessary wiring.
  6.  
  7. Remove the speaker retaining nuts.
  8.  
  9. Remove the speaker from the vehicle.
