Default Adjust horn pitch or replace?

Love the car, but the horn is a bit weak. Okay, it's lame.

I was considering replacing the horns altogether, but then I see in the tech notes that the pitch can be adjusted. Does anyone have any experience trying this?

Is it even worth trying to lower the pitch on the stock horns so that it doesn't sound like a go-kart, or am I just better off replacing them?

Thanks!

Default replace it

I know exactly what you're talking about! As soon as the weather gets nicer, a replacement horn from an auto salvage yard is going to take the place of the 'lil Kia horn.
Not sure what will fit, but it should be easy to take the horn off and match the mounting style up to another one that has a little more "authority". Maybe a Cadillac horn would work...

I saw some generic replacement horns at the auto store for about $15 a peice.

That's why I was wondering. If I'm going to go through the trouble of removing the bumper to get at 1 of the horns, then I'd rather just go ahead and replace it if changing the pitch isn't going to make that much difference.

I have been thinking that I would replace the horn on my Shuma, never thought of adjusting, but now I will see if it can be done.

In the past I have fitted replacement horns on motorcycles, I fitted a twin horn taken from a Ford Focus found in the breakers yard, the horn itself if easy to fit, even if they dont bolt to the same spot, finding somewhere to bolt it isnt too hard, also the wiring, well if you take the connector and the horn from the scrap car, then wiring it up would be as simple as making an inline connection

According to kiatechinfo, there is a pitch adjustment screw on each horn. Let us know how it goes.

Somehow, I think I'll still have to replace them to get the sound I want.

I remember back when I was a kid, someone I knew had an old tank of a car. When he blew his horn it sounded like a passing freight train. Somehow, I doubt the stock horns will EVER get that sound, no matter how much you adjust the pitch.

Yeah I reckon your right mate, I will probably end up replacing the horn too

Well I managed to get hold of a horn from a black cab, the horn is massively loud compared to the standard.

I have not fitted it yet, but I will be doing tomorrow, I hope then improvement is worth it, I suspect it will be tramendous difference

am I mistaken, or does the optima have two separate horns? this wouldn't be at all unusual except there is one on each side of the car. I have never seen this before.

According to the manuals at kiatechinfo, there are 2 horns. However, unlike most cars, they're not mounted together.

One is behind the front bumper and the other is in front of the front-left wheel well.
