I'd like to replace my original horn with something a little louder and with more bass. Any suggestions?

How about a cheap air horn from a local parts store for around $20-30?

I used some replacement horns from Auto Zone on my Jeep, they were louder than most stock horns.I can't recall the brand name but they are red in color and come in packages of either one or two.

The air horns sound like a normal horn that has been kicked in the nads

Get a truck air horn vs the cheaper ones (opinion).
Not sure of any stores/brands..
Ebay?
