No, you do not subtract the power from the head unit's power.. the speakers will be getting all their power from the amp, not the HU.
You should be giving those RSDs around 100 rms each by the way, not 60. I know thats what the website said or whatever but do some research and you will find some people give them 150 or even 200 rms without many problems.

Thats not entirely true. alot of people giving them that much power say they sound great and like 2 weeks later come back here shrugging their shoulders wondering why their tweets are blown.....
