• How to Repair and Replace Blown Sub Car Speakers

    Any damage to your car speakers can greatly affect the audio coming out of your car stereo system. There are several causes why the audio in your stereo system can change. However, one of the most common reasons is due to a blown sub car speaker. Replacing these blown car speakers is actually easy if you know the proper procedure and know-how.

    Tools and Materials

    • New speakers
    • Screwdriver
    • Soldering iron
    • Putty knife
    • Re-coning kit
    • Glue

    Step 1: Check the Speakers

    Determine first which speaker has blown. To do this, turn on your car stereo and check by ear which speaker is no longer playing properly.

    Step 2: Remove the Speaker

    Once you have determined which speaker is damage, removing the car speakers is the next step. Take out the damaged speaker from the enclosure. To do this, remove the enclosure first by taking out the mounting screws. After, you can now disconnect all the wires attached to the speaker. Make sure that the ignition or power is off before you do this.

    Step 3: Remove the Surround

    Remove the grille of the enclosure, if any. Using a putty knife, remove all surround from the damage speaker. Make sure that you remove all the glue and surround from the blown sub car speaker.

    Step 4: Remove the Cone of the Speaker

    Carefully remove the cone of the sub car speaker also using a putty knife. You also need to remove the speaker’s voice coil attached to the speaker by cutting the terminal wires. After this is done, you can now take out the old voice coil, spider and cone.

    Step 5: Clean the Empty Space

    Remove any dust particles stuck in the space where the coil used to be. You can use a compressed air to thoroughly clean out any dirt.

    Step 6: Installing the New Voice Coil

    Once the area is clean, you can now replace the old voice coil. Just place the replacement voice coil back into the space where the old one used to be installed. Follow it with the new spider, making sure you wrap it around the new voice coil.

    Step 7: Installing the New Speaker Cone

    Replacing the car speakers is easy. All you need to do is put some glue onto the new speaker cone and then place it onto the new voice coil. Make sure that the cone is center. Allow at least 24 hours for the glue to dry up.

    Step 8: Putting the Surround

    When the cone is dry, apply some glue to the speaker’s surround as well, and place it on the edges of the speaker cone and frame. You will need 24 hours for the glue to dry.

    Step 9: Securing the Wires

    After everything has dried up, you can now put the wires back. With the soldering iron, solder the existing wires to the speaker’s coil and cone’s wires. If there are no wires on the new speaker cones, just make some small holes in the cone and using small wires, connect it to the terminal wire. Put the wires through the drilled holes and then solder them to the new voice coil.
