Wondering if there are any ordinances against a really loud horn installed in your vehicle? If so, what is the Decibel level you cannot go over or is it more of an issue of disturbing the peace?

27000. (a) A motor vehicle, when operated upon a highway, shall be equipped with a horn in good working order and capable of emitting sound audible under normal conditions from a distance of not less than 200 feet, but no horn shall emit an unreasonably loud or harsh sound. An authorized emergency vehicle may be equipped with, and use in conjunction with the siren on that vehicle, an air horn that emits sounds that do not comply with the requirements of this section.

27001. (a) The driver of a motor vehicle when reasonably necessary to insure safe operation shall give audible warning with his horn.

(b) The horn shall not otherwise be used, except as a theft alarm system which operates as specified in Article 13 (commencing with Section 28085) of this chapter.

There probably are municipalities that have local code as well.
 
Thank you for all the information. It's probably a good idea to check municipalities specifics but that is a good reference point so that rules out installing a loud horn on an SUV. One more question, where it states, "but no horn shall emit an unreasonably loud or harsh sound". Does this include Semi-trucks with the air-horns or are they excluded?
