Better/additional horn?

[Groucho]

I like blow blow my horn at bad drivers and people texting and driving. I find the horn is barely adequate.
Has anyone found a good alternative? (Other than those train horns)

It's actually pretty loud outside the vehicle just not inside..

Next step is a train horn..

You can get a Hella horn if you don't want a train horn.
