Is there a way to match crossover points on amps? For example: I have 6 12's and 3 amps on them. They all have variable crossovers. Can a scope be used in some way to set them? Any info would be appreciated.

In this case I would say a regualr DMM would be the easiest. Say you are crossing over at 80Hz, use a DMM and a 1kHz test tone to match each amps output to a certain level. Then play a 20Hz tone, and match the levels with the frequency control.
The 1Khz tone will start all the amps at the same output and is beyond the range that the crossover will affect. Then when you switch to 20Hz, the crossover circuit will be what is controlling the output level at those frequencies. If the output of one amp is higher than the other, the crossover point is higher and you need to turn down the first amps frequency control.
