## Questions & Answers

**Q: Is it waterproof**
A: The horns are WATER RESISTANT. Mine have been installed for 3 years, been through all kinds of weather, still work fine. Very loud.

**Q: Is it a two wire connector or a one wire connector**
A: Two wire. One power, one ground.

**Q: Positive and negative isn't labeled. Does it matter which is which?**
A: Should not matter just make sure that if you are using both horns wired them in parallel-- that they connect same  for same terminals on both horns 
I had 1 horn originally so I had to put a jumper terminal in a and wire it in parallel to the 2 horns for the single horn connector on my car
Do not connect in series i.e run from the power wire into 1 terminal and then out the 2nd terminal on the same horn into the terminal on the second horn and out that one back in to the power terminal, that may cause a problem?

**Q: Do you need a relay with motorcycle installation**
A: No

### ⭐⭐⭐⭐⭐ People can now hear me in my miata!
*by S***V on January 5, 2026*

### ⭐⭐⭐⭐⭐ GREAT HORN AND PRICE
*by J***S on November 25, 2025*

Great material quality and sound.

### ⭐⭐⭐⭐⭐ Sounds Louder than OEM!
*by G***Z on November 5, 2022*

I used it on my 2013 Scion TC and it is definitely worth it. A cheap $20 modification that will be useful when driving everyday is a deal. Sometimes with my stock horn I felt like people couldn’t hear me, with this its loud enough so they can hear me, but not loud to the point it will be obnoxious. I feel like it is a good mod, cheap and get a great outcome out of it, best of all it is plug and play and works better than the stock ones. I will be doing it on my other cars I ever get in the future.
