I take it the with all running it a Yamaha mix from 7.1 and splitting signal to front presence am I correct ?
Hmmm... not sure what you're asking. Your 3030 has 9 amplifiers in it. You can run 7.1 AND add 2 Front Presence speakers without a separate amp.
The subwoofers have their own amps, so don't use one in the Yamaha. Not counting your subs, you are using 7 channels, (Left, Center, Right, Left Surround, Right Surround, Left Rear Surround, Right Rear Surround). So you are only using 7 of the 9 amps in your 3030. When you add L & R Presence, you are adding 2 more channels for a total of 9. Your 3030 can drive all of them fine.
You say you hooked them up and it sounds great. So what is your question?
