eBay 300db Car Horn Review - Cheapest Train Horn on eBay Bench Tested - Loudest Car Horn

Introduction

This tutorial provides a detailed review and step-by-step guide on the eBay 300db car horns, which are marketed as the loudest car horns available at an affordable price. We will explore their features, installation process, and testing methods, helping you decide if they are a suitable upgrade for your vehicle.

Step 1: Unboxing the Horns

• Carefully remove the horns from the packaging.
• Note the design: the horns come in a classic black and red color scheme.
• Identify the components:
  • Two horns (high and low frequency)
  • Metal backing with a plastic horn
  • Two steel mounting brackets
  • Packing material
• Check for any visible markings or labels, though these horns typically have none.

Step 2: Understanding Sound Claims

• The seller claims these horns reach 300 dB, but this is misleading.
• For perspective:
  • A train horn is about 120 dB, audible from 3 to 5 kilometers away.
  • A gunshot is approximately 140 dB; a jackhammer is around 100 dB.
• Realistically, 300 dB is considered fatal at certain frequencies, making the claim highly exaggerated.

Step 3: Preparing for Testing

• Gather your materials:
  • 12V bench testing battery
  • Jumper cables (create these if you don't have any)
• Connect the jumper cables to the horns:
  • Attach one end of a jumper cable to the positive terminal of the battery.
  • Connect the other end to the positive terminal of the horn.
  • Repeat the process for the negative terminal.

Step 4: Testing the Horns

• Ensure you are in a safe area to test the horns.
• Position the horns towards the testing area to maximize sound projection.
• Activate the horns by connecting the final jumper cable to the battery:
  • Touch the negative cable to the battery's negative terminal.
• Observe the sound:
  • Expect a loud response, significantly louder than typical car horns.
  • While not 300 dB, these horns are surprisingly powerful for the price.

Step 5: Installation Tips

• Plan where to mount the horns on your vehicle. Ensure they are easily accessible for maintenance.
• Use the included steel brackets for secure mounting.
• Ensure the horns are positioned to direct sound outward, improving audibility.

Step 6: Safety Considerations

• Remember that a loud horn is a crucial safety feature. It helps alert other drivers and pedestrians to your presence, potentially avoiding accidents.
• Regularly check the horn’s functionality to ensure it remains effective over time.

Conclusion

The eBay 300db car horns offer an affordable and surprisingly loud option for upgrading your vehicle's horn system. While the claims of 300 dB are exaggerated, the performance during testing indicates that these horns can significantly enhance your vehicle's safety features. If you're dealing with an ineffective factory horn, consider investing in these for improved sound and safety. For further questions or guidance, feel free to reach out or leave a comment.
