What air horn puts out the most decibels for the simplest setup? It's for the F-350 below.

I put a triple 12V trumpet on the Explorer but I am not impressed.

I'm looking for freight train sound and volume. Grovers?

I first posted this under Super Duty but could not delete it. Sorry.

I have done the search. Is there a way around the mounting of a tank or would that just require a bigger compressor to drive the horns directly?

Thanks,

Reg

 

Here is my setup. It is fairly loud. The Grovers are way louder and deeper than the Hadleys. They make a 40" horn that is REALLY loud but requires 175 psi. If yuo don't use a tank then it sort of defeats the purpose. When someone cuts you off, you would have to turn on the compressor, then hit the horn button. In addition, you would have to use a compressor that turns out a LOT of air to make the horns work for very long(more than a second or two)or be very loud. My compressor was very expensive(to me) but it does everything I need. Small tanks can be had very cheap and are very easy to plumb.
