Just installed a set of Hella Supertones a month ago and am not finding them to be as loud as they are perceived to be by others.
I connected it straight into the stock horn connector (just a direct swap of the stock horn)-- wondering if the problem is because I didn't use the relay provided?
I'm not sure if anyone else has done the install and how they've gone about doing it but I think there's lots more potential in the horn than what I'm seeing..
Help would be much appreciated.
