Having a cheap ($19.99) but loud, new set of horns leftover from not installing them on my last 2005 Tucson, and looking to head on the interstate to Myrtle beach S.C. Carolina this Sat, I was determined to change out that dangerous, pathetic, excuse for a horn! 
So here's what I found, and how it's done, first this job is not that hard to do, anyone can do it easily, as long as you have this info,,, I just hope my horn switch, & relay, holds up with the twin horns I put in.
1) under the hood just remove the screws holding the radiator cover, I don't think it's necessary to remove all of them, just the drivers side, enough to be able to remove the headlight assembly. Then there's 3 bolts holding the headlight assembly, on top 1-10mm, & 1-12mm they are right on top, & quite visible, next underneath there is another 10mm bolt about the middle, in sideways, (check pix) just remove these, and the headlight elect plug (push down on the back of the plug clip to release) now, just sort of jostle the headlight back, & forward (but forward a bit more) while lifting it, and pulling back the loose radiator cover to clear, and it should come right out.
2) The One cheap flat p.o.s. Kia horn is now visible, & accessible. In the 3rd pic you'll see it after I removed it, and the angle bracket that holds it laying on the inner fender well.
3) I decided to open the air filter, being as it was so easy to do now with nothing in the way, Look what I found in my air filter housing??? Surprise! Acorns! I have no idea how they got there, the air spout lifts the air from underneath, then sends it down to the plenum to the filter. uzzled: By the way, it's a thick odd shaped filter, and looking at the bottom of the cover there's another felt like non-removable permanent filter attached to it apparently? uzzled:
4) I found I was able to use the original mounting bracket for both my horns, the short bracket arm on the old horn itself, I found was 2 pieces when I took it off the horn, I seperated them, bolted them together end, to end, forming approx. a 45 degree angle, I was then able to mount both horns on that, one on top of the other, in a canted position, both facing the front (the grill), and mount the bracket upside down in the middle, but it was not flat against it's mount,,, it still would have worked fine, but I decided to face the horns down, and mount them side, by side, one above the other, putting the bracket back in it's original position for security, the top horn plastic cover rests against the body, it's snug, but it works!
5) The hardest part was making up the wiring harness with the female spade terminals, then cutting the Hyundai connector off, (I had no choice, couldn't find an adaptor) and splicing the horn wires into the spade terminals along with the new horn wiring.
6) Tried the horn, a Big difference, finally a normal horn, I doubt I won't be heard now, at any time, or any speed!
7) Put it all back together, and I'm done! T.G.
Hundai, how could you do this to us!?
Pic #5- Is to show you the thick Air Filter
Pic #6- Is to show you the headlight bolts, one on the inside in the front, one on the inside in the back (that's 2) but glare blacked it out some.
Pic#9- Is the 3rd 10mm headlight bolt underneath, you can't miss it, it's like being inside a raised plastic picture frame.
Pic#10- Is the crappy single KIA horn! Pick it up, wind up, & toss it hard as you can into the unknown,,,lol
