I may be getting one to run on my 2 DD3512's I have never used USAmps before. Does anyone here have any experience with them or this model? How is the reliability of them? Also I heard different stories about the true output some say 3000 and some say 2100. Whats the real scoop on these amps and hows it stack up against the rest? And do you think that will work good for those subs?
