One thing I've never really enjoyed about the Fiero is the 'tow-motor' sounding horn. I've been looking for an alternative horn for some time, but it'll probably be one of the last items on my to-do list.
Who here has changed theirs? What did you go with?
Cadillac horns work perfect. Nice and loud and with the attitude that comes with a bigger car There are TONS of caddies in the junk yard. Make sure to get both horns from the same car, they seem to be offset in sound just a little from each other to make a 'chord' when they both blow.

Agreed. Get the horns from any full-size GM like Caddy's, Olds, RWD van or truck. I have GM van horns on my Indy.
Test them off your battery before installing them.

I agree, used 92 Deville horns from 4.9L engine / trans donner & they are a great improvement in sound.
Hella and Fiamm makes OE Horns for EU/import cars.
Fiamm makes cheap replacement horns is ok but get OE horns at a junk yard.
Treat horns as a set for best results. Avoid horns from two cars/makers.
Avoid cheap air horns! Ebay Amazon etc and most auto parts stores/outlets have poor quality units. Will break the compressor or crack a horn diaphragm at worst time.

If you want loud get a set of Hella Supertones. Had a set on my Subie - used to make people jump when they weren't expecting it lol. Everytime I hit a horn in any of my cars I miss having them.
Advance sells a high and low tone pair of horns. Some say they're the same as the Delorean horns. I have a pair on my 87 and they are plug and play and quite loud. Dorman Champ High Tone and Dorman Champ Low Tone.

I installed a pair of the Delorean horns recently. They are very similar in size to the stock horns but are much better. They are louder than stock but the main difference is that they are PIERCING!! Their tone really travels well and they are very good at getting someone's attention.
They are not plug and play but they are close. You have to swap the wiring harness mounting tabs. The stock Fiero horns have tabs which are riveted on and they have a raised section that the wiring harness clips to. The Delorean horns have a similar tab but the Fiero wiring harness clip will not grip it. The easy fix is to swap tabs. To do this, just drill out the rivet holding the tab to the Fiero horns. The Delorean horns are assembled with a nut and bolt setup. Simply remove the nut on the Delorean horn and put the Fiero tab on.
The Delorean horns also come with short mounting brackets. Simply remove them and they will mount to the original Fiero mounting points. I pointed the trumpets downward in hopes of preventing water from collecting inside.
Ditto. With shipping they were about $50 for the pair. I admit that is pricey compared to junkyard pieces. Not sure if I would do it again after reading the good reviews of the Cadillac horns. I guess the best thing about the Delorean horns is that they are brand new and are almost plug and play. No need for splicing wires or creating new mounting brackets or adding air compressors. That and they are great attention getters which is what I wanted them for in the first place.
I've successfully adjusted the screws to revive the horns on my '84 SE & '86 coupe over the years to maintain the two tone sound. Haven't lost a horn yet.
I intended to keep my '88 Formula as stock as possible but I just couldn't have only the single tone horn. I added the low tone horn from a donor '87 so all three cars have strong but slightly different note horns.
Apply power to the horn; (it might hum) and turn the little screw sticking out of the housing near the connector. Try turning it a little both ways - there's a pretty good chance the horn will start working. It's worked 100% for me on 6 horns. I sound the horns occasionally - it seems to prolong their functionality. (You may wish to wear earplugs with the horn at arm's length! )
I used a pair of S-10 blazer horns in my old DD Fiero. They were loud enough to grab most peoples attention and people on the receiving end were probably looking for a full size truck then a little car. As for my GT, I have two systems going. First is just a FIAM air horn that sounds like a coffee truck. I also have a compressor & 4 trumpet train horn system, BUT unlike the video IMSA GT posted, I don't go around scaring the **** of people, just the ones trying to drive me off the road in their minivans.
Caution on air horns. Some states will not allow cars with air horns only to pass inspection, such as Delaware. I've taken my work Jeep thru and when they hear the air horn they will ask if the electric horn is still functional and if so lets hear it. If not then you fail. Yes I know it takes electric to work the compressor but that's their way.

I used a pair of Fiamm high/low horns on my Fiero for many years. They were loud enough to get people's attention, but not obnoxiously so.
On a side note, the horns are grounded via the mounting brackets. If the bracket and/or bolt gets rusty (and they will after a couple decades), it can reduce or even stop the flow of electricity through the circuit. If your horns aren't working, or sound half-dead, try cleaning the mating surfaces and bolt threads first.

You might also revive 'dead' horns by turning the adjustment screws sticking out of the housing - I've revived several that way. (See posting above with picture for reference.)
There are TONS of caddies in the junk yard. Make sure to get both horns from the same car, they seem to be offset in sound just a little from each other to make a 'chord' when they both blow.
