I have a PPI a600.2 and I am currently running 1jl12w6v2 and I am not very happy with it because I am running at 8ohms. This amp is rated at 600x1 at 4ohms but I heard it is underrated. It is also a class A/B amp so it cannot be run under 4ohms mono. I want to know if my amp will run 1 brahma 12 at 4ohms? I know it will prob run it but will it run it nicely? Any info would be appreciated. thanks James
