I'd like to get an air horn for my car, whilst still keeping the stock horn. Crowd control you see. Anyone have something like this installed? I'd like a trumpet, but not sure if it'd fit under the hood. In any case, the visuals are not so important. What I want the most is a deep truck sound, like the big rigs. Don't need 600dB, but a good volume would be best. Also, I want to wire it in such a way that i have a separate button controlling it, perhaps besides the fog switch where there appears to be a slot that resembles a blank so maybe some wiring tips would be good too. Any of the kits on ebay good? I will post some links if it makes it easier. I am not really an expert on this. Looking to spend maybe $50.
