Alright, a happy ending to my horn quest! After getting a refund for my mini-bomb, which was very loud,
but also quite large and cumbersome, I went on a search and found another option on Aliexpress.
It's called a "Seger" and its model is "55B Mini Shell Horn". I ordered it awhile ago, but it was
around $50. It is a very solid feeling horn, and is a perfect fit in the GRiSO, just slides right into
the existing space with no adjustments needed. And it is much louder than the stock horn.
I tried to contact the manufacturer to find out what the "55B" designated (some strange decibel -like number?),
but the language barrier got in the way. He did say this horn was louder than the horns with a 44 designation, so I went with that.
I know, it seems that would be a logical answer to assume, but I've found weirdness everywhere in parts labels in the past.
Anyway, the 55B is probably not as loud as the mini-bomb was, but it still made me jump when I first tested it on the
install ! I am very happy with it, and it does sound like the horn off
maybe a Rav-4, or similar mini SUV.
Thankfully, my horn no longer sounds "like an apology".
