Does it rattle when you honk them?

I assume you mean the Bosch horns in the engine compartment and not a common rattle on the horn ring (this also has a fix).   The Bosch horns come apart and can be reassembled with a new paper type gasket that you would cut from a sheet of gasket.
 

This will help but also you will find great info on other posts.

Yes it rattles when I honk them. Probably some went under the car and they make a strange sound not normal. Btw they are not original Bosch and I would like to replace them.

I meant to say that some water went under the car and for this reason they make a strange sound. Usually when replacing the horns you work only under the car right? You don’t have to disconnect wires from the column or steering wheel right?

You have connectors on the horns themselves.

I would have thought even not for a mechanic it is easy, at least it was for me... detach and refresh the brackets as well (those made of multiple metaln plates).
Unless some screw gets stuck, but that is another, general story.
