    Hi everyone,

    After being fed up of the stock horn on my motorcycle I purchased a Denali Soundbomb Mini horn (with the BMW wiring adapter). This looks like plug and play in place of my stock horn. As far as I know, the stock horn draws 3 Amps, while the Denali draws 5 Amps.

    Will the stock wiring be able to handle the excess current through it, or do I need to change it ? Additionally, I have seen some people mentioning installation of a relay with aftermarket horns drawing higher current. Electrical stuff is a little confusing to me. If I do need to install a relay, then what should be the spec of the relay?

    Thanks,
    Anby
