I put the Fiamm double airhorns in last year sometime and I noticed that they started to just kind of die over time. The horn would get less and less powerful until nada, they stopped altogether! So me and a friend (Luder94) checked it one day and disconnected the hoses and the compressor WORKED! It blew plenty of air, but the horns wouldn't make a sound at all! So I decided to just buy another set of Fiamm's, this time I got the triple horn set. Installed them using the same compressor and they were loud as balls when I first put them in, but now they are starting to do the same thing as the other ones did!

Any ideas!?

 

Interesting. I'm running double Fiamms and have had no problems. I have the alarm set to not honk them when I set the alarm, so they don't get "blown" very often. Do you use them often...like maybe for rounding up geese?

 

Wes, well, I have been known to try and frighten animals along the roadside with the horns, but not that often. Geese are particularly fun as they all do a little jump and a quick couple of flaps then settle back down...all in unison!

But no, not used that often and I have even driven the car in almost two months! Today was the first day...I still can't believe it's the middle of January and I drove with the top down!

I can't explain it...they worked fine right after I put them, I used the new hoses and everything. They just sort of lose steam over time. Very weird. But they blasted like the dickens when I first put them in...

Help! Living in the horniest city in the country, Fiamms are a requirement!

 

Greg,

I wonder what's going on. How did you wire the originals? Are they wired per instructions or did you just overtake the oem horn wiring?

On the S2K, I just overtook the stock wiring and only had problems with blowing out many, many, many, many fuses. If I remember correctly, the stock fuse is a 5 amp-er. Then I moved up to a 10, then a 15, and now I am on a 20 amper and haven't had any issues.

I blow the horn ALL the time...I especially love it when I set off car alarms in the parking garage. I also love seeing birds $h!t when I blow the horn.

Although I don't think you are having a fuse problem like I did, I think you may be having a prblem with the wiring. We should take a look at it at lunch today.

 

Greg,

I've been running triples for quite some time now, and haven't had a problem with them yet. In the winter months, the compressor is ever so slightly slower to come up to pressure...when I hit the remote twice for the audible horn signal, the horns "just" start to toot...it disappears as I press the button several times for several toots.

How do you have the horns placed? If the compressor is still pumping out air at a good pressure, maybe your horns or their reeds are getting clogged with road debris. Try putting some water down the horn, swirling it around, and letting it dry for a day. Let me know if that solves the problem...

BAD IDEA. I'll check my wiring (looking at doing double-horns) but I suspect that the wiring probably isn't sized for 20A! My Staebel knock-offs pull I believe 11A when blasting. 15+A might cause your insulation to melt if you hold it for any length of time.

You know, now that we talk more about it... a friend of mine had the dual Fiamms and had them burn. I used my Staebels for a couple of years, no problems, and will move them to the S2 soon...

I agree with Chris- basically a parallel circuit. The easiest wiring would be to mount a new relay near the fuse box (under hood), tap power from their (or the battery), then use the factory circuit to activate a new relay. You could find and rewire the stock circuit with larger wire, but would probably have to do a LOT of work and make the dealer VERY suspicious if you are ever in for warranty work.

I'd go for new wiring, which I'll probably resort to as well. If I recall, the Prelude had 18AWG wire in place, but had two parallel circuits for the two horns. I tied them together for the new ones.

 

All new wiring was run, it's not using the stock horn wiring. What I don't understand is why they started off OK, then they just started to die a slow death...

I don't think it's electrical. At first, though, I thought it was the compressor failing, so I disconnected one of the tubes and found that it would spin up and blow air. But putting the hose back on the trumpet and I get squat! Then putting JUST the new trumpets on, the horns (therefore the compressor) was working.

The only thing that I'm thinking is that there is debris clogging them somehow...but I don't know. I'll look at the old trumpets when I get home tonight...

Any more ideas?!
