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

Twin trumpets, Fiamm is the same supplier to Ferrari, made in Italy not China, $24.00 shipped from Autobarn.com I think the regular price is $32. They have that great Euro high/low piercing blast like the Italian cars, not the alternating hi/lo of the Euro police cars.

I added this to my original description "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)"

You need to record it and convert it to .wav format.

You could also just take a short video of you "blowing your horn", and post it instead. We could then hear how they sound that way.

I think I can do that, I have a digital 8 that I can put on the computer, then could I upload in the "manage attachments" section. will this work for video?

I don't know if the site allows you to upload videos or not. Gueass you would have to try, but I doubt it becasue there is most likely a size limit and your video size may be too big.

If you need to host the video and it isn't "too big", I might be able to put it up.

this site doesn't host video or audio clips. If you want to email it to me, i can host it for you, kings. Just pm me for my email address.

Sounds almost as good as my horns NR, I have to go by my office tomorrow and get my burner to load up, once I get the clip on the HD, I'll PM you for your email and get this show on the road. I plan to do an in car, front grille, and end of driveway clip, as well as the installed product, I don't imagine more than 45 seconds, any limits on length? Thanks

No - I got lots of bandwidth. Send me what you get.

horns - II Kings

II kings, you insired me along time ago to do this mod even though, in the life of my last car, I must have used my horn about 3 times over over 7 years :)

I got a set of dual red trumpet italian made Fiamms from Autozone (a store chain here in PA) but when I took the unit home, realized that it must have been opened before. I returned it and am awaiting a "new" one. It retails for about $27 with tax. Did yours come with wiring? There was no wiring in the package, and you did not use the included horn relay I assume.

I noticed from your pic that the compressor sits on that angled bracket near the washer fluid opening. If you put the horns in the right side stock horn position, the length of the air hose from the compressor is quite long- maybe contributing to dead space and the lack of a re-assuring chirp at "lock up"? For the horn to work quickly and efficiently, methinks there should be as minimal an amount of deadpsace in the tube as possible. Is there a delay in operation between horn press and sound produced in "normal mode"? If there is a perceptible delay, it might be a "deadpsace" issue (after making allowance for the crummy horn switch on the steering wheel)

I have also read other threads on the web where folks have modded their various vehicles with this horn; they report a small life cycle for them.. How long have you had yours and does it look like it is deteriorating?

THe only service is a drop or two of oil in the compressor, I have had it approx. 1 year and it's perfect. Keep in mind I blow it 99% of the time for demonstration. The dead space in the tube is a great thought, kinda like having to blow the column of water out of a snorkle (my snorkle has a valve to keep it totally dry under water, from Herrington catalog). Back on point, thie only problem I have has nothing to do with the trumpet, it's the poor, defective horn button. Yes, I did use all existing relays etc, it is a simple plug and play and I used my own wire.

wish I lived in NYC

Well I installed the horns - I mounted both horns as well as the compressor with very short lengths of the included tubing to the original stock front right side horn bracket. I bought a metal strip about 7 inches long with 5 pre-drilled holes from Home Depot to mount all this. Now both my horns sit just behind the grille both facing horizontally, parallel to the grill surface, back to back with the compressor in the middle. I used only one of the original horn connectors to go to the "+" side of the compressor. The "-" side (Ground) was attached to a short length of wire and clamped to the bolt that holds the original bracket in place. Even though I have cut the dead space in the tubing to a minimum, the horn does not "chirp" at "door unlock". After installing them (I was alone), I got into the car and tooted the horns and wasn't impressed with the sound... Then it occurred to me to listen to it with the doors open- These are LOUD! and also sweet.

I wish I was in New York City- Then I could blow the horns with impunity! I want to move to New York City NOW :)

NYC - My wife asked a cabbie why he leaned on the horn so much.

His response - "Why, that's the fun part of the car, lady!"

The first time I hooked up my air horns on the 300C, i was so disappointed that they were not loud. (I was inside the car). As I stood, bent over under the hood, as my son pushed the horn button, my opinion quickly changed.

I learned 2 things:
  1. The 300C has the best soundproofing of any car i ever owned including a DeVille.
  2. My skull is very thankful that the underside of the hood is well padded!

Glad to hear ,no pun intended, things went well jaydee, I love these things. Now if only somebody can figure out how to get a reliable horn button in the steering wheel.

Still no luck on sound NR, unable to compress the clip, If you have an office or PO box (can never be too careful giving home addresses over the net) I can mail you a DVD if people are interested in hearing it.

I put a set of the 3-trumpet FIAMM air horns (website says signaltone, used to say FIAMM, the product still says FIAMM and made in Italy on it) on my 1985 Benz, along with a toggle switch where the no longer useful factory stereo fader was to switch between stock and air horns. These air horns, which JC Whitney claims are 134dB as opposed to the other 118dB ones aren't nearly loud enough. They are loud, just not loud enough. I plan to buy 2 more compressors so each trumpet has it's own compressor. The should get things going.
