My stock horns SUCK! Whenever I use my horns in an emergency situation, it only tends to:

1. The sound is so puny that the other driver doesn’t hear/notice.

2. It pisses people off and they go into full-on road rage mode.

What I’m looking for is something so powerful and obnoxiously loud that it’ll put the fear of God into them. Maybe something that’s not overly complicated to install or require extensive modifications.

Oh, I forgot to mention that I have a’19 base.

 

Driving a Fit in Texas, I think you're going to have to come to grips with that reality. Having driven an even smaller car (CRX) for many years, some truck and SUV drivers are just assholes. They drive a huge vehicle to feel powerful - to compensate for their every-day life. They ain gon take no shi from some little Honda. If their life is taking a dump on them that day, the small cars become their punching bag. MURICA.

There's two horns - a high and a low tone, both behind the bumper cover below the right headlight. Any of the 1-wire Horns from Honda or Acura should drop-in. Re-locating them to the radiator inlet should also help.

 

You need a good old American horn from the 80s.... like what was on say a Chevrolet Caprice Classic... now those were horns.
