Swapped out my stock 2015 Subaru horns for these. Ran them off of a relay. Sound exactly the same. The horns are big and beefy, but it's all show and no go. Either that or the stock Subaru horns are actually pretty decent. I'd only do this if you are repairing failed horn(s). If you think these will be an upgrade, I think you'll be disappointed.

I don't think electric horns like these have any polarity. It's a simple circuit. One is power, the other is ground, but it doesn't matter which.

10 minutes in to "how to wire your horn" and you never show us how to wire the horn. Thanks

10:27 of my life gone, only to find out you didn’t bother wiring the relay or directly to the battery. That is what I wanted to see. Anyone can plug stock terminals to new horns.

this was a good video, the wiring of the horn is the most important part, thanks

I just bought a box of Sharp tones and there's a bold warning on it that says: Do not adjust the position (angle) of the bracket or the nut. It changes the electromechanical properties and will result in loss of performance and warranty. Isn't that what you suggested to do in the video? Also, why not using the relay that's included in the box?

Well done. Only video I've seen where someone worked the penetrant in

[chillozz]

that white circular thing... Is that for adjusting the loudness of the horn??? I have olso a hella horn but that part i cant turn... and there is a turn indication sign...

[richmalt]

I have the same one and they don’t have polarity

[Hallowsaw]

Where did the first positive wire come from cause the secon one you said was from the original harness

[Chris-fjir]

Did you run tbe ground from horn to horn. Or ground to frame? Inreally need more detail, im not that smart

[MrMasterFlash]

How can you tell which is positive and wich is negative?

[kotastrophie]

Nowadays a plus sign can be and look however it wants to don’t judge it on how it looks

Hella Horns Are Made In India Now😍I Too Have Same Pair In My Kawasaki Bike.

[thehegt]

So install the L tone on the driver side and high tone on passenger?

[kCI]

You'd think Hella would label the power terminals, it's not that hard.

What’s the point people put a relay and all?

[DARREN_STI_WANG]

Im using these horns too and i find them soft. Will the relays make them louder?

[codenamemamba]

Can you get away with 16 guage wire???

[jakehughes]

What about the relay? Do you need it or not
