@iczer34 posted:Haven't installed the tones just yet, I purchased the pair with high (500 hz) & low (300 hz) tone frequencies. Debating if I should install both or just one. If I install both, i'll probably have to run a relay which I'd rather not do all the wiring (lazy!).
I'll post a YT clip once installed
You need to install both. Separately, they sound like kiddy kar horns. It's the dissonance between to two frequencies that create the "attention grabbing" effect.
FWIW, I installed my Hella horns without a relay and they are plenty loud.
