first off which one is the actual horn the one behind the grill or the one on the side of the engine? and second hoe can u change the sound of it??

 

all of thw horns work together to make it sound like that. if you unhooked the rght onw, it sounds weird, like a hyundai horn. you'd need to go to your auto parts store and buy a horn. usually you'd only need 1 horn, hook it up on the side tho where the side horn is so people cant snip the wire and the alarm wont sound.

 

Beat it with a stick : Wet it ... Or get one from a different car and install it ...

There's a low and high, if you change one, you definately should change the other to the w/e the other car is.
