I am getting this DDz2 for the low!!!! I will be trading again soon! The DDz2 did 7700w clamped at 1.8 ohms, so that's about right! I can run it at 1.4 ohms (I have a D.7) but I would like to try it at .35! Ty said it can do it if have the electrical! The DD will do 13,000w at 16v! I do like the NS-1! It will be about the same wattage. I don't wanna strap amps so I can change ohms quickly. Even though I've been at .35 ohms since the week after I put it in, lol
