Factory speakers are usually so bad that the new amp probably won't make them sound any better than the HU. Plus, you're only using them for fill so you don't need lots of power. I would bridge the amp and use it solely for the new speakers. The extra power will do much more good there. Use your HU to power the rear factory speakers and only fade them in enough to give you some fill. The stage should come from the front.
