Three hole mount

installation steps:

1. Prepare tools and materials: roof speakers, electric drill, screwdriver, screws, wires, etc.

2.2. Determine the installation position of the speaker: Choose a suitable location to install the speaker. Generally, the center of the car roof or near the front of the car roof is more common.

3.3. Measure and drill: Use an electric drill to drill a hole at the installation location, ensuring that the diameter of the hole matches the diameter of the speaker bracket.

4.4. Install the speaker bracket: Insert the speaker bracket into the car roof through the hole and use a screwdriver to fix the screws.

5.5. Install the speaker: Install the speaker on the speaker bracket to ensure that the speaker is installed firmly.

6.6. Connect the power supply: Connect the wires to the positive and negative poles of the speaker, and find a suitable power interface in the car to connect.

7. Test: After completing the installation, turn on the vehicle battery switch and test whether the horn can work normally.

The structure of the speaker holder: installation relationship. At this stage, in the installation process of the car's speaker system, the speaker installation system is mainly fixed on the body through three solder joints. In order to facilitate the connection between the speaker mounting bracket and the car body, certain welding positioning holes are set on both. In practice, the speaker mounting system mainly uses 4 RIBs and 2 flanges with a height of 5mm to ensure stability. To prevent the speaker from rotating based on its fixed position during installation, two positioning protrusions with a height of 2.5mm are set on the speaker installation system to prevent rotation. At the same time, under different conditions of the car, the actual strength and stiffness of the body part must ensure that it can support the entire speaker system and ensure the stable operation of the speaker system.
