Dave, you don't say what radio or audio panel you are using, but I'll give you my experience just in case you are using the same or similar radio:
I wired my stall warner board to my Garmin GTR-200 radio. At first the tone was way too loud.......startling loud. But it was very easy to just turn down the volume for that input in the Garmin's settings menu.
I'm guessing this ease of volume adjustment may be available with various radios and/or audio panels? Not sure, but it was really simple to adjust with the Garmin.
I like the stall warner. I had to adjust the angle of the vane some, but it goes off about 5 mph before the stall. Seems simple and familiar.
