• Dash speaker grille × 1 — Use OEM specification if damaged

Preparation

2. Turn ignition off and remove key
3. Disconnect negative battery terminal and wait 2 minutes for airbag system capacitors to discharge
4. Gather all tools and replacement parts

   Disconnect battery negative terminal
   Using a socket wrench, loosen and remove the negative battery terminal bolt. Remove the cable from the battery post and secure it away from the terminal to prevent accidental reconnection during the repair.
   Torque spec

   Battery Terminal Bolts6 Nm (4 lb-ft)
2. 2

   Wait for airbag system discharge
   Wait a minimum of 2 minutes after battery disconnection to allow the airbag system backup capacitors to fully discharge. This is critical for safety when working near dashboard components.
   ⚠️Failure to wait 2 minutes can result in airbag deployment and serious injury
3. 3

   Remove speaker grille
   Locate the dash speaker grille on top of the dashboard. Insert a trim panel removal tool at the rear edge of the grille and gently pry upward. Work around the perimeter to release all retaining clips. Lift the grille away from the dashboard.
   ⚠Apply even pressure when prying to avoid cracking the grille or dashboard surface
4. 4

   Remove speaker mounting screws
   With the grille removed, locate the speaker mounting screws. Remove the Torx screws (typically T15 or T20) securing the speaker to the dashboard mounting bracket. There are usually 3-4 screws per speaker. Keep screws organized for reinstallation.
5. 5

   Disconnect speaker electrical connector
   Carefully lift the speaker from its mounting position enough to access the electrical connector on the back. Press the release tab on the connector and pull straight out to disconnect. Do not pull on the wires themselves.
6. 6

   Remove old speaker
   With the electrical connector disconnected, lift the speaker completely out of the dashboard opening. Inspect the mounting area for any debris or damage that may affect the new speaker installation.
7. 7

   Install new speaker
   Connect the electrical connector to the new speaker by pushing firmly until you hear a click. Verify the connection is secure. Lower the speaker into the dashboard opening, aligning the mounting holes with the bracket.
8. 8

   Install speaker mounting screws
   Insert and tighten the Torx mounting screws to secure the speaker. Tighten evenly in a cross pattern to ensure proper seating. Do not overtighten as this may damage the speaker housing or strip the mounting points.
9. 9

   Reinstall speaker grille
   Align the speaker grille over the speaker opening, ensuring all clips align with their corresponding holes in the dashboard. Press firmly around the perimeter until all clips engage with an audible click. Verify the grille is flush and secure.
10. 10

    Reconnect battery
    Reconnect the negative battery terminal to the battery post. Install and tighten the terminal bolt to specification. Ensure the connection is secure but do not overtighten.

Reassembly

1. Ensure all trim clips are fully seated and the grille is flush with the dashboard surface
2. Verify no tools or loose screws remain in the dashboard area before testing

Verification

• Turn ignition to ACC or start the vehicle
• Turn on the radio or infotainment system
• Test the replaced speaker by adjusting the fade and balance controls to isolate that speaker
• Verify clear sound with no distortion, rattles, or buzzing
• Test at various volume levels to ensure proper operation
• Check that the speaker grille is secure and does not rattle during operation
