I did that and it worked just fine.  The Herc II power connector is 
wired so that you can easily have one of the supplies feed half of the 
amp and the other supply feed the other half.  I DID strap the 
regulators together, using the banana connector.  I ran two #12 reds and 
blacks from each supply to the amp to keep the IR drop low. I used two 
RS70s. One was NOT enough. :)
