On some amps the 12v trigger signal can be daisy-chained from one amp to another. I think the Outlaw 220 monoblocks do this and some of the other Outlaw amps might too. I'd be wary of splitting the trigger signal - if you connect the two amps in series each will get only 6 volts - insufficient - and in parallel each gets only half of however many milliamps the 970 puts out, which might also be insufficient. Others here probably know more than I.
