Hi, i am new to the competitions but in class A and B stock in the rules it says no competition grade equipment. What do they consider competition grade equipment? Would a lanzar opti drive amplifier be considered competition grade? Thanks for any information you can provide me with

The "competition grade" status only applies to the subs. The amplifier you choose to use must be either (1000 watts rms for Street Stock A) or (2000 watts rms for Street Stock B). To verify this wattage, the amplifier(s) will be clamped at the event.

Positive and negative voltage out on the speaker leads of one sub from the amp.
voltage^^^^^
multiplied by
amperage
Put the amp clamp around the positive speaker lead in which you are checking for voltage as well.
