Don't put Victors "in parallel". It won't work the way you think it will, and it could end up destroying one or both of them.

A Victor speed controller pulses the outputs between full power and off, changing the duty cycle and polarity based on the PWM input. Even with the same input, two Victors will not necessarily switch their outputs in synch with each other, and might be fighting each other.
