Not sure if I have enough oomph.

While your amp has plenty of power, a subwoofer woofer or two can make sure you  rarely use more than a few watts. 

All the best.

OMG.  Only now, after spending $15,000 are you concerned about this?  Like purchasing a Ferrari and then thinking about the gas consumption and repairs.

Well.... in a bit you will not have to 'THINK" about not having enough power or Ooomph.  Cross that bridge if you get to it.  

My grandmother told me not to worry about something you Don't know.  Worry about those you do know about.

PS.  "New in box.."  Break them in well first.  You want ooomph.  You will probably not get that straight out of the box.
