i'm trying to build a list of components i'm going to buy to make my system most excellent. i'm thinking about a RF 551x power series amp to push some Diamond audio (rear) S600s 6.5" and (front) DA S400s. i already have 1 RF 1001bd amp and need one more to power 2 RFR3112 subs so i kinda want to keep in the RF family. if this amp 551x won't push the Diamond Audio to their full potential what will? suggestions.

50-125 watts RMS should do nicely. I strongly suggest that you put the 6.5" in front and the 4" in the back. It's a small 6.5" mid and won't need much modification of the stock baffle area.
