Not to Hijack, but one time I bought a set of Fiamm Highway Blasters from Aerostitch and those things were really loud. Sounded just like an auto, but louder. I'm running the Nautilas right now, but I sometimes wish I got the Fiamms. Loudest horn I ever heard. I think that sometimes they fudge on the decibels.
The problem with just "decibels" is that it is a totally meaningless number without knowing the distance and the frequencies. Sound pressure goes down to the square of the distance. And the human ear perceives different frequencies with much different volume levels. Finally, different frequencies travel and penetrate differently, affecting what one might hear inside a closed, target vehicle.
