[QUOTE="basscube5, post: 8461140, member: 668183"] Just a clamp meter, it reads AC or DC current. I was expecting more current too. It was pulling 13A @14V from the battery and putting 48V @ 3A to the woofer, which I think are junk numbers either because the power supply wasn't stiff enough or the woofer was wayyy high impedance wise. This was all meant to be a voltage test anyway, the amp needs a much better power supply to be able to get decent current numbers. Regardless, +- 75V at the rails answered a lot of questions/concerns I had. I can't see any manufacturer gearing up a power supply like that if the amp wasn't going to put something decent out the other end. Shame there aren't any amp dynos close, I've never seen any AB product tested. [/QUOTE]
