Fiamm Air Horns

I love these horns, here is a DIY.

First off you will need to remove the plastic panels above the radiator exposing the stock horns. The panels are held with clips and pop out.

Next remove the stock horns, the new trumpets fit best facing the passenger headlight.

To mount the new trumpets you will need longer mounting screws and several washers, the bell on the new trumpet hits the stock bracket causing the trumpet to rotate as you tighten the bolt resulting in an insecure mount. By using a longer bolt and washers you lower the trumpet on the bracket and the bell no longer hits it allowing for a very tight solid mount, I used a bolt about double the length of the supplied bolt. Take it to the hardware store to make sure you get the right size threads and diameter, you might buy a few lengths and return the unused ones, cheap enough to keep in the tool box.

I mounted the compressor in the passenger fender well using a shelf bracket, make sure you use lock washers for this. See pics.

I routed the air hose thrugh an opening in the headlight region, just find a hole, you don't want to go over the bulkhead, may compress the hose and looks unprofessional.

Wiring is easy, save some labor and try this first, I think you only need to run one wire to the compressor since it is an electrical signal and the compressor will send air to both trumpets. I thought of that after I did my wiring. I spliced the two horn wires (again I don't think that was necessary) and ran the stock fitting to + terminal on the compressor and ran a ground wire from the - to the ground nut near the compressor at the fender.

I don't like the horn chirp when locking my doors , the chirp does not signal the compressor hard enough to blow the trumpets, you can hear the compressor click but it is wasteful if the horn doesn't chirp and adds wear to the compressor so I turned that feature to the off position on the EVIC

Marlin,
loud? I'm embarassed every time I demo this thing to friends- It's almost earsplitting in a pleasant way..

Well, if you've ever heard an 80's Benz horn you know that those horns are loud as hell too, in fact just about as loud as the FIAMM's. The reason I put in a switch is because I want air horns that raise the dead, and to have the stock horns for situations when I don't want to shake the car in front of me.
I'll get some trumpet pics, I mailed a DVD to NR who will get it hosted somewhere for a look and listen.

How do the decible measurement work. The higher the decible the louder/Deeper/highpitch/lowpitch?

I went to Autobarn.com and I dont see any "Fiamm" brand.

This is what I see: http://search.store.yahoo.com/cgi-bin/nsearch?unique=3fc58&catalog=rodi&et=42f40360&basket=b%3D5C508088d8008fb642f3fc52250fd8de188d8a3e2a518b2355da780e4c282e00e%26l%3Dfk4hjece7820d/o%26s%3DpMe1g2DD03dclf5hYLWsd79mL88-


Those Chrome ones would match nice.

Please somebody tell me how the decible thing works. I want my horns to sound like a SemiTruck. Tooooo many dumb drivers here in FL.

Thanks

The higher the decible, the louder the volume (IIRC 3 decible increase results in approx. twice the loudness...though tha could be wrong...all I know is that it's a logarithmic function). The larger the trumpet the lower (bassier) the sound. To get truck sound, you have to use truck horns, only problem is those need a compressor, air tank, and huge ass horns and you will never get all that in your engine bay. These horns will sound nice and loud, truck horns sound mean and loud. Don't get me wrong though, when you honk these, people react.

Thanks man.

I wanted to put train horns, but when the guy told me he had to install a huge compressor I said "Heck NO". It was about 12"x12"X24". Just for a horn, I dont think so. I might aswell put airbags on the suspension.

Im just waiting now on the clip sent to NR by King, so I can see it and hear it.
My Fiamm install pics

All,
I snapped a pic from the top of my fiamm horns- you can see the original passenger side horn bracket on which i installed a home depot obtained bracket on which is mounted the compressor and the two fiamm trumpets. The fiamm trumpet you can see is the longer one, extending towards the driver side. The shorter one extends to the left of the picture and can't be seen from above..I have also labelled where I attached the gound wire from the compressor(red wire) . The passenger side stock horn wire was attached to the "+" terminal of the compressor. The driver side horn wire was detached from the horn and just taped in place, unattached.
cheers!

Glad you got some Pics posted, I have been in Cleveland (suprisingly nice downtown) and hope to get some more pics posted tomorrow.
Trumpets here, I used the stock location, wrapped the hose around the horn to keep it off the hot radiator unit below.

II kings..

Did you use extra hose? seems like you needed several feet of that stuff to get everything hooked up..Mine had about an 8 inch piece left over from the original amount enclosed with the packing.
Jay
Yes, I got extra hose from Lowes I think.
The Promised Video

Kings shot a nice video of his air horn install, but had no server to post it on.

I have put it up for him:

Fiamm Air Horn Installation
Thanks NR for all your work, these horns are a huge improvement over stock, too bad we can't fix that sorry rubber horn pad.
Thats Nice. You know thou what i want is the sound of the horns from the movie The CAR. They sounded like a Simi truck horn.
My dad had one of those horns on his 77 Econoline van, got it fron JC Whitney for $9.95, you could hear him two blocks away.
