1. The power supply should be 12VDC power supply.
2. The output working current of the power supply should be above 30A, and the working current should reach the rated working power of the speaker.
3. Check whether the terminals and wires are in good contact and there is no oxidation.
4. If the connecting cable is too long or too thin (less than 1.5mm), the speaker will not work.
5. The bracket piece should be tightened at the installation position. If it is too loose, the wiring will fall off or the internal components will be damaged due to severe vibration.
6. There must be appropriate space when installing, and it cannot come into contact with other parts of the car body.
7. When installing the snail horn, the horn mouth should be facing downward at 45° to prevent water from accumulating in the snail shell from being properly discharged.
8. Install as far away from the engine as possible.
9. When installing, you should pay attention to the position not being too low to avoid being blocked by mud or other debris and making sound impossible.
10. Customers cannot disassemble or adjust the screws by themselves.
11. When a pair of tweeters and woofer speakers are installed at the same time, be sure to connect them in parallel, not in series.
12. If the speaker is dropped and distorted by humans, it will cause the sound board to deform or the internal gap to change, resulting in no sound or abnormal sound.
