    Loud And Not Shrill Like Smaller Air Horn Kits

    Loud And Not Shrill Like Smaller Air Horn Kits
    This is a great low end air horn kit. I say low end because it's nothing like a real train horn... and the trumpets are cheap plastic. So I would not mount these on the outside of a vehicle that goes offroad somewhere where limbs or brush may be encountered. But they are fine behind the grill. They make a nice dual tone big truck sound, not like the smaller kits which are shrill. They come with two trumpets, a compressor, a relay, a tubing Y, and some clear air hose.There are some things you need to know about this type of horn system. First off, you need a little room to install it. The trumpets are around a foot long and take up a some space. Also, you need to install them pointing straight down so water does not get into them and ruin them. If you don't point them down, they will have a short life. I've been through this several times with other sets. Take these thoughts into account and don't order this item if you can not accommodate them. Also, get someone to install it for you if you don't under stand how a relay works or if you are good at using basic hand tools.See [...] if you need help with the relay. Pin 30 goes to the positive battery terminal. Pin 87 goes to the horns. Pin 86 goes to ground. Original horn wire goes to pin 85. I think the compressor requires a ground as well. But that's all there is to the electrical part if you have a working horn wire under the hood already.

    The original factory electric horns failed after being subjected to torrential rains on Bonneville Salt Flats. They were replaced with aftermarket units, but those were not adequate to request respect.
    The big kids reside directly behind the grill segments, and speak smartly when required.
    Hint: Mount the top of the compressor up in a full length cut-off plastic water bottle, to keep moisture and debris out of the air intake port. Wiring and air tube won't interfere with performance.
    These are not in the same league as my former Hadley's and REAL fire truck trumpets, but do a fine job without compressors, tanks,regulators and solenoids.

    These are a Great Investment, Loud Good Sound, Can hear both Trumpet's kick in seconds after hitting horn button. Easy simple Hook up. I wired mine direct to old horn wire, added a ground. People on phones, bicycles think i'm a truck coming they move over.

    I am a Fiamm fan from way back. They used to be really good.

    This is a sort of decent horn as long as it works, but does not last very long. I blow it once a month or so, and it fails within a year. I replace it with another, since it is cheap and easy after you've done it for the first one. they seem to have a different failure mode each time, so I am amassing a nice box of spares. Soon, I might be able to make a complete set.

    I believe next time they fail, I will save $5 and buy the same horn kit with the Wolo label on Amazon. There is nothing that makes these worth 5 cents more, let alone 5 dollars. It is the same set of Chinese horns, but maybe Wolo will have a warranty of some kind.

    If you purchase these, run down to the hardware store and buy enough wire and connectors to test it right away, just to be sure you have a set that works. Test each horn individually to be sure both work. Be sure to use the relay when testing, to make sure it works, too.

    I would suggest you buy two sets, and select the best horn and compressor and then return the set with the deficient parts. With the variable quality of their production these days, hand-selection can work to your advantage.The factory seems not to be familiar with the concept of quality control, so it could be beneficial for the customer to do his own.

    They just seem to die, whether used or not. Just sitting seems to kill them. I don't know whether it is age or environment. Maybe corrosion sets in after a while or maybe there is a plastic part that becomes brittle with age. Perhaps they should be labeled "for indoor use only". Or "Do not drive (or even park) in rain or fog"

    And, if they don't just die, they will break. The horns are completely made of plastic, so plan on supporting the bell mouths somehow. Otherwise, road vibration and aging will cause the mounting to break. Or the bell horn will break at the place where it is (incompletely) glued into the body.

    As previously mentioned, the horns are all plastic. That means a rather dull, flat, soft sound, so don't expect the brilliant Fiamm sound of years past.

    There is also no way of fine tuning the horns by screwing the bells in and out as in years past. The way they are stuck in is what you get. So there is quite a variation in how they sound. As an example, sometimes one horn will respond to just using your lungs to blow it, but the other one will not. Connecting them one at a time to the compressor will show you the difference in both volume and tone. It will also show you whether of not both of them are working, as well. Check them out before the return period expires. After that, you are on your own.

    If you do get a pair that works, test for air leaks where the horn trumpet is glued into the head. You might be able to improve the sound and volume by adding a little more glue to seal any air leak.

    They do include a few nuts and bolts, but they seem to be made in different factories, and do not always fit each other. You are on your own for wiring and terminals. I would suggest mounting the compressor where it is not subjected to engine heat or atmospheric moisture. That means in the cockpit. The compressor is a little noisy, but that is OK, since you will not (hopefully) be using it much. It also gives off an alarming odor when used, so open your windows before blowing the horn. And leave them open for a while afterward. The smell is like an electrical fire. Using short blasts instead of long ones will increase the life of the compressor, as well as keep the odor in the car to a minimum.

    I cannot imagine how on earth they can call this compressor "Heavy Duty".

    Fiamm seems to have no expectation of a reasonable service life, as there is no warranty. So don't expect any help from Fiamm or from whoever made it in China.

    This is not a good deal. You have to wire up everything and good luck finding a place to mount the horns. There are NO mounting brackets included and I will pass this on as a gag gift for Christmas. IF you want the hassel by all means waste your time and money.
