Wife wants a louder horn on her Prius - what to buy?

[Escape08]

I installed the PIAA “ highway blaster “ low tone horn on my wife’s little Pontiac Solstice. It had only 1 anemic high tone horn from the factory and the second horn made it much more mellow and also louder but not annoyingly so. In such a small car you need the extra db’s! Also, made in the USA!

That's what I did to my 1984 Isuzu p/up. Normally it's either a single high tone or a low tone that's installed in the vehicle. Normally the there's an H or an L indicated on the horn. Then you have the pair it with a different tone. The result is a harmonic horn sound like the Buick of the 1950s much like what you hear in most of today's high end model vehicles

Is there some law in Japan that says the horn must be commensurate with the car in some way (cost, size, something)? I could swear a CR-V honked at me, and it left me wondering, did that CR-V honk at me? Yet a full sized Lexus honks and it's prominent, like every German car.

Sounds like either her driving style needs it or it’s so bad locally you need to use the horn a lot?

My wife asked if I would install some loud horns on her Prius as she is tired of the wimpy stock one. I've installed Hella SuperTones on a car before, and they were an improvement over stock but weren't earth-shatteringly loud. Anybody know what I can buy that's extra loud? I'm not looking to install a big set of air-horns, BTW, as space is cramped.

Horns from a late nineties Cadillac sedan are nice.

I use GM 4 note horns from old Caddies, Olds, Buick, etc.

Nice blend of frequencies and LOUD

I remember they were listed as high, low, deep, and penetone in the parts books.
I think I have a set buried in my parts stash.

A pal salvaged a pair of friendly-lake-tooters from a wrecked "poor man's Chris Craft". He never used them.
Another pal despised the weak horns on his '89 K1500; so in they went.
He recalled something about faint horns being part of GM's ecological mindset during that time.

I installed them and the cartoon noise they make was an instant hit.
They sound a romantic, nasally, "KNEE-yaahhh"...which is boat horn for, "Uncle Bill is approaching the dock. Is his martini ready?"

Whatever the factory put in my little Ecosport is loud!

Reminds me of a 70's Ford LTD. I wonder how much ford parts would charge for one

There's not much of a crumple zone in a Prius, so I pretty much only have one honk to save my life.

It's so loud that people question if it's really from a Prius...


two sets of these:

one siren:

four of the piezos:

So nine horns, total!!??

 

[StarCaller]

I wouldn’t really count the piezos as horns, but yeah, one siren and four ‘real’ horns.
I didn’t need the stock wiring—I used a relay connected directly to the 12v battery.

Two sets of those piaas might fill up and compromise your crumple zone!! LOL
