I answered this in email but I want other people to have this information as well.

You can NOT wire multiple motor controllers together. Bridged channel mode ONLY works between the two channels on a single motor controller. This only works because the channels are synchronized down to the nanosecond. Wiring multiple motor controllers together will effectively short them out since their PWM outputs will not be synchronized. This will have the effect of not working correctly at the minimum or destroying all the connected controllers in the worse case.

As for your second question in if you know the approximate amps your motor needs for your load(the 150 amps listed may be peak or continuous rating but isn't necessarily the amount you need for your application) then you can determine if you can wire multiple motors to the same channel by adding up the maximum current each motor will need under your particular load. If one channel has enough current capacity for multiple motors under your given load then yes you can have more than one motor on a motor channel.
