To answer myself somewhat if someone wants to do the same I have found a way to just skip the amping part of the board and just grab the low level signal from it to go to my own amps. One 4 channel 50w per channel amp for the rear speakers and center speaker and one 2channel 80w per channel amp for the two under seat subs.
Only problem I have run into is that the sub's signal seem to be a balanced one with a +(1v) and a -(1v) and a ground so I am not exactly sure how to convert them because now I only receive half the signal.
So if anyone have any clarification on this it would be appreciated.
Below are how I have wired the rca cables to the board and also I started label all the connections on the ribbon cable
