Review on πŸ”Š FIAMM 66040 Big Boss 2 Long Trumpet Horns with HVY Duty 12V Compressor Kit (10 Pack) - Powerful Sound Amplification for Enhanced Safety and Performance by Sean Maile

Revainrating 1 out of 5

For indoor use only. .When you go outside, use smooth roads only.

I've been a Fiamm fan for a long time. They used to be very good. It's kind of a decent horn while it works, but not for very long. I blow it up once a month or so and it fails within a year. I'm replacing it with another one since it's cheap and easy after you've done it for the first one. They seem to have different failure modes each time, so I put together a nice box of parts. Soon I may be able to do a full set. I think next time they fail I'll save $5 and buy the same Wolo labeled horn set from Revain. There's nothing that makes them 5 cents more expensive, let alone $5. This is the same set of Chinese horns, but maybe Wolo has some kind of guarantee. When you buy them, go to the hardware store and buy enough wire and connectors to test it out right away just to make sure you have it set up and working. Test each horn individually to ensure both work. Be sure to use a relay when testing to make sure it works. I would advise you to buy two sets and choose the best horn and compressor and then return the set with defective parts. Nowadays manual selection can work to your advantage given the varying quality of their products. The factory seems unfamiliar with the concept of quality control, so it may be beneficial for the buyer to do it themselves. They just seem to die whether used or not. Just sitting seems to kill her. I don't know if it's because of age or the environment. Maybe corrosion will start after a while, or maybe there is a plastic part that becomes brittle over time. Perhaps they should be marked as "for internal use only". Or "Don't drive (or even park) in the rain or fog." And if they don't just die, they break. The horns are all plastic, so plan on supporting the bells in some way. Otherwise, road vibration and aging will cause the bracket to break. Or the horn of the bell breaks where it is (not fully) glued into the body. As mentioned, the horns are all plastic. That means a rather dull, flat, mellow sound, so don't expect the brilliant Fiamm sound of yesteryear. There is also no way to fine-tune wind instruments by screwing the bells in and out like in the old days. The way they stick is what you get. So there are some differences in the way they sound. For example, sometimes one horn will respond to you simply blowing your lungs in while the other doesn't. Connect them one by one to the compressor and you'll notice a difference in volume and tone. It will also show you if both work. Check them before the return period expires. After that you are on your own. If you got a pair that works, check for air leaks where the horn tube is glued to the head. You may be able to improve the sound and volume by adding a little more glue to seal air leaks. They have a few nuts and bolts in them, but they seem to come from different factories and don't always match. You do your own wiring and terminals. I would recommend installing the compressor where it will not be exposed to engine heat or humidity. So in the cockpit. The compressor is a bit noisy, but that's okay as you won't (hopefully) use it often. It also gives off an unsettling odor when in use, so open the windows before you honk the horn. And leave them open for a while afterwards. The smell is like electric fire. Using short bursts instead of long bursts extends compressor life and also minimizes in-car odors. I can't imagine how they can call this compressor "Heavy Duty". Fiamm doesn't seem to have hope. reasonable lifespan as there is no guarantee. So don't expect any help from Fiamm or whoever made it in China.

Pros
  • High marks for grip and durability from testers
Cons
  • Not as thick as other options
