HIGHLANDER_821 is pretty close to being dead on, but those number on the high side are a little high. Even with wattage for numbers they will not do you any good unless you use the modulation numbers and set it within a few % points of those modulation numbers, otherwise it will sound like crap. The dk on low if I remember was 2 1/2 watts swings to around 16-18w, and high side it would dk around 17w and swing to around 33-37w. Wattage above this is way too high. If you need the modulation numbers let me know and I will look them up, PM me so I will know what your looking for.
