Thanks for the info. A couple of questions:Wolo Bad Boy and Fiamm Highway Blasters (two horn set, High and Low) had some of the highest decibel ratings in an independent test I read about several years ago. I have a set of the Fiamm horns on my Rebel. If you get the Wolo's, use two if you really want to be heard.
You'll need to wire the aftermarket horns into a relay. The stock horn wires don't provide enough power to activate these aftermarket horns.
