What is the Decibles of the stock horn on a cav?
dB is a relative measurement.
realative to what? I just want to buy a louder one so i need to figure out what im starting with.
I got an aftermarket horn... it was rated 112 Db and it was louder then the stocker.
Now I got 2 of em

Wrong.
a decibal is a unit of measurement for the SPL of a sound. It is a real figure. Loudness is relative.
Not exactly sure what you plan one using the realy for...
If you get two of the same tone, it will sound louder, and be a nicer sound.
If you get two of different tones, it will NOT be twice as loud, but certainly louder then one. Reason being the tones will cancel each other out. Anyone that knows music or phyisics will agree.
I have one high and one low, Im not too worried about loudness (it is plenty loud) but i like the "WTF" look you get from people cuz "A Cavalier should not make that sound"

how easy are aftermarket horns to install? it looks pretty easy, do you have to take off the bumper to get it out?

I did it on my last cav and it was easy. i never removed the stock horn cause it was to tight in there but i was able to get to the wires and remount the new one. And if I got the two different freqs the relay makes it sound like a police siren, i think. and i dont want any air horns i dont want to deal with compressors.

they can describe very big ratios using numbers of modest size. But note that the decibel describes a ratio: so far we have not said what power either of the speakers radiates, only the ratio of powers.

What does 0 dB mean? This level occurs when the measured intensity is equal to the reference level
dB is a relative measurement.
Everything is not constant is relative, and even some constants are relative. But absolutley EVERYTHING is relative if you start looking at it in a point-of-view relationship.
However, some things, such as horns on cars, have such a low ratio of relativity that a good estimate of a value can be produced.

i have a wolo model 417 air horn. it sounds nice and loud. it's rated at 118db and 415 450 hz. you can click here for a clip of how it sounds on their
page. here's the clip if you don't want to look for it on
there.
a horn on a car should have a high relative ratio, the ratio is horn to ambience. ambient noise while driving in an instance where you would have to use your horn is subjective. so in a way we're both right and wrong. if the ambient noise your horn is compared to is white noise, then dB would be more constant. if the ambient noise your horn is compared to is eighteen wheelers veering into your lane... you get the picture.
So these 130 dB horns from jcwhitney can either be loud or quiet depending on where their meant to be used?
Ok but since im so curious , Say i had two what would the level of the sound be? Also what dB is required before you have to worry about glass breaking?
2 horns of same frequency, Db can probably be added together, as the sound waves would reinforce eachother.
2 horns of different frequencies, Db is harder to figure, the sound waves will at times cancel eachother out, although they will reinforce eachother at times.
