Im running just about the same set-up power wise (+750 and 400 on the amps + yellow top Optima) and I have no issues. I did NOT upgrade my big 3. I DO have a 1 farad cap though. I dont think you should have a problem without the cap though.
Some tips:
-Definitely make sure you use some beefy cable, dont go smaller than 4 gauge, and definitely go larger if you can afford the extra metal.
-+1 On proper grounding as well. Keep grounding points away from other circuit paths in the car. Ideally, you want to ground every point of the system in the same place, and that place should be as close to the battery as possible.
-Run your power cable on the opposite side of the car as your signal cable. If power goes down the driver side, run the signal down the passenger side. Power cables can create interference which can then be transmitted into your signal cables and eventually out of your speakers.
