Tools required

Parts

• Dashboard tweeter speaker × 1 — Honda OEM 39120-TBA-A01 or aftermarket equivalent

Preparation

1. Park vehicle on level surface and engage parking brake
2. Allow interior to cool if vehicle has been in direct sunlight to prevent trim damage
3. Identify which dashboard speaker requires replacement (driver side or passenger side)
4. Ensure ignition is off and key fob is outside the vehicle

Procedure

1. 1

   Locate the dashboard speaker grille
   The tweeter speaker is located at the forward corner of the dashboard near the A-pillar on each side. The speaker grille is a small triangular or rounded trim piece visible at the top edge of the dashboard.
2. 2

   Release the speaker grille
   Insert a plastic trim tool at the rear edge of the speaker grille (closest to the windshield). Gently pry upward to release the retaining clips. The grille is held by 2-3 plastic clips. Work carefully around the perimeter until all clips are released.
3. 3

   Remove the speaker grille assembly
   Once clips are released, lift the grille upward and away from the dashboard. You may need to angle it slightly to clear the surrounding trim. Set the grille aside in a safe location.
4. 4

   Access the speaker mounting
   With the grille removed, you will see the tweeter speaker assembly secured to the dashboard frame. On most models, the speaker is held by two or three Torx T20 screws visible around the perimeter of the speaker housing.
5. 5

   Remove speaker mounting screws
   Using a Torx T20 driver, remove the screws securing the speaker assembly to the dashboard. Keep these screws in a safe location as they will be reused during installation. The speaker assembly will now be loose but still connected by the wiring harness.
6. 6

   Disconnect the speaker wiring harness
   Carefully pull the speaker assembly away from the dashboard opening to access the electrical connector on the back. Press the locking tab on the connector and gently pull the connector apart to disconnect the speaker. Remove the old speaker completely.
7. 7

   Install the new speaker
   Connect the wiring harness to the new speaker by aligning the connector and pressing firmly until you hear or feel a click. Verify the connection is secure by gently tugging on the connector.
8. 8

   Secure the new speaker
   Position the new speaker assembly into the dashboard opening, aligning the mounting holes. Insert and hand-tighten the Torx T20 screws, then tighten them in a cross pattern to ensure even seating. Torque to approximately finger-tight plus 1/4 turn - these are self-tapping into plastic and do not require high torque.
9. 9

   Test speaker function
   Before reinstalling the grille, turn the ignition to ON (engine does not need to start) and test the speaker by selecting radio or media playback. Adjust the balance and fader settings to isolate the replaced speaker and verify proper operation at various volume levels.
10. 10

    Reinstall the speaker grille
    Align the speaker grille over the speaker assembly, ensuring any alignment tabs are properly positioned. Press firmly around the perimeter of the grille until all retaining clips snap into place. Verify the grille is flush with the surrounding dashboard trim.

Reassembly

1. Ensure all speaker grille clips are fully seated and the grille is flush with the dashboard surface
2. Check that no gaps exist around the grille perimeter that could cause rattles

Verification

• Turn on the vehicle audio system and verify sound output from the replaced speaker
• Test across multiple volume levels to ensure no distortion or rattling
• Use balance and fader controls to isolate the speaker and confirm proper operation
• Verify the speaker grille is securely attached and does not rattle during test drive
