yes it will be fine but they have to be the same amps, and they have to be set with a DMM to the exact gain or you will cause damage tpo the sub.

Another simple thing... but seen it overlooked... is make sure that if the amps have phase switches or knobs, that they are set the same too. Having them set different (if 180) is the same as having the coils wired out of phase and will result in no cone movement and LOTS of built up heat. Same goes for continually adjustable phase... if one is set to 0 and the other 49degrees... things are out of whack as well...

DMM and set up the output voltage for each to be the same, and you are good to go.
