which do you buy, how do you know what sound they give, how do you wire them up, how much????

[jam2005]

You can get them from The Mini Shop London. They have an advert on the first couple of pages of Mini Magaine. They sell twin air horns with a compressor and only cost £14.50 BARGAIN. They aint half loud . Here's a pik of the Mini Shop London twin air horn set...



And here's a pik of how to wire them up...



You can always use the fuse for the positive feed. That way you wont need to run a cable to the battery and all wiring is kept neatly under the bonnet. Also if your buying the Mini Shop London ones you'll need a 25A fuse as it keeps blowing the 20a one .

Hope this helps,

ps. Sorry about the big piks .

i had the twin note horns on mine, they are LOUD

[Dom]

thanks, how long do they take to fit? easy to do?

[jam2005]

Yea there easy enough. Hardest part is finding a suitable place where to mount them. I mounted mine jus behind the washer bottle. Just at the back left of the engine bay. That way there's enough room to mount the compressor and both horns and looks nice and neat. Leave yourself about 2 hours. Easy enough time to get the job done then.

[Dom]

can you post a pic of where you mounted them?

[TimS]

though these ones dont play a tune!

[Dom]

i want ones that play funny tunes!

do they only play one or can they play differnet ones?

Do what I have done and connect the two connectors off the original horn straight onto the spade terminals on the compressor unit. I have had no problems with this at all and it all works fine. Or is this an mot failure?? if so then just disconnect and reattatch to the original horn. Only took me around twenty mins to do.


VERY LOUD

It is a good idea to use a relay in an air horn circuit, as it is in a twin horn setup. The twin horns or compressor draw a lot more current than a single horn does and the wiring isn't really up to it, you can get away with it because you generally don't use the horn continuously but it can lead to some loom melting or even a fire.
Use the existing terminals as you have done but put them onto the coil terminals of a relay instead and then run some more, slightly heavier gauge wire from the solenoid, through a line fuse then on to the load terminals of the relay and then to the compressor, which also needs an earth.

Get some musical dixie ones!

Or stick 5 mismatched electrical ones! (I have 2 from an aftermarket set, one from an R34 skyline GTR, one from a 1.3 Yaris, and one from an old Metro)

MAN those things are loud!!! I think they seem even louder because of how out-of-tune they sound. VERY irritating noise!

I also have twin airhorns fitted to the car but not wired up to supplement these

I don't want any fires or melting of wires so consider it done my friend
