i run 2 v3 sonaces in my truck (the v3 are pretty much an alpha). And they sound amazing. shoot me a pm and i can send you a vid or two if you would like to see them. I haven't had any problems with steve at all he has always treated me right. I will back up RD. My 1750 is a very solid amp i run it at one ohm and it never has even gotten warm.i have a brand new v3 sonance and its build quality appears to be very good. customer service wasnt the best
