Posted: Fri Apr 03, 2009 3:11 pm Post subject: Two Horns Wiring |
|
|
I finally got around to fixing my sick(cough wheeze) honk button today and I decided that I would install my old horn(though it was dead, it wasn't) and the one I bought to replace it. And I ran into not a roadblock but a confusing restriction thing. Do I wire horns in series or parallel. I know I will get more volume with parallel but will it melt my wire? |

Use a relay. That's how VW did it on the Ghia. _________________ Andy

A relay sound like its not a bad idea but still, series or parallel? |

Remember the stock horn is wired with the (+) always hot and the (-) is switched. If it is an aftermarket horn where the (+) is usually switched and the mounting bracket makes the ground connection, you will need to take that into consideration when you wire in the relay. _________________ In pursuit of superior handling!

Just switch the wires around and you should be fine.
Now, do you know what tones the horns are? I Nissan Frontier came with a "low" tone, very puny by itself. I wired a "hi" tone in parallel and now I really get people's attention.
Make sure the one you got as a replacement and the original aren't the same tones, or you're going to end up with pointless install. |

Dual horns are only just a bit louder than a single. Remember, you'll need a high tone and a low tone for it to sound decent. You could follow a ghia wiring diagram and that should help. You should switch to air horns _________________ oo9less since 2007

I have an american tone horn and the stock horn in parallel. Both have two posts so the wiring was easy. And, like stock, I switched them on the (-) cable. It is pretty loud and has a good tone. I am wondering though what would happen with two of the same horn. Would you get constructive interference creating a louder tone? |

Nope. When I did the dual horns on my Nissan, I actually bought a low tone, thinking I had a hi tone stock. When we wired it up, it didn't sound any different at all. That's when we discovered I got the wrong one.
Two of the same horns doesn't do anything. Something about the way audible waves work or something. |
