Has anyone clamped a Diamond d3 600.1? I've read thy are alittle under rated. I just bought one because my Usa-100 has some issues. I was wondering how much louder I can expect the diamond to be. I know the stock specs say 400x1 @ 2 ohms, and the usa-100 is 315@ 2 ohms. Any way if anyone has any info on this amp please post up.

Thanks.

BTW looking for (2) 2 ohm dvc subs for cheeeeap if anyone has any.
