[QUOTE="winkychevelle, post: 8804219, member: 611804"] No gain is only to adjust the amps sensitivity to input voltage. Below the max output voltage of the radio the gain knob act like a power knob. And 2000w at 4ohm is what I would look for since your amp will never see less than 2.67 and will only see higher due to box rise. The dd1 is great for maximizing the output of an amp but using simple math you can set an amp that makes rated power to any wattage below what it actually makes V(ac)=√(w×r) √(1800watt×2.67ohm)=69.3v(ac) It only takes a multimeter set to ac voltage at the amp outputs. And having more power than needed isn't a bad thing [/QUOTE]
