the one i heard was on a 500/1 and sounded greati asked what's the min/max and they said to just run 300 watts. their power ratings are off a little, owners manual says 600 continuous but on that chart, that's in the danger zone. they said when they rolled out the new subs they were running 300 watts to each. as you can clearly see, minimum power is at the 100 watt mark.
