When the M200 first came out, there was some discussion of being able to daisy-chain a single trigger output, and I think it was considered reliable for two or three in series. You can split the signal, but the amps will each see 12v at a reduced current when the trigger is on - whether that reduced current is enough to trigger them will depend on the amp. Unfortunately, by the time that I had more than one trigger-equipped amp I had moved to using a power conditioner/surge protector with a trigger and switched outlets (which I use now to power up the 7500, both M200's, and the LFM-1). You might ask Outlaw what the voltage will be after splitting (assuming nobody else chimes in with that specific value first) and then run that value past the manufacturer of the two amps you are planning to use to find out if it is sufficient.
