The system you are putting together sounds like it will be a nice one. I would have to assume that you are never going to leave the dock or you plan on having an onboard generator installed to power this system.
You are missing the point in one area. All the amplifier power you will require to drive this "audiophile" quality system has TREMENDOUS power requirements. And the systems waste a giant amount of thier energy requirements in heat, no interest in making them effecient from the manufacturers. And your proposed subwoofers will be the biggest power hogs of all. In your home stereo, you may think that 100 watts is no big deal, needing, say, not much more than a couple of amps to deliver that power. But in a 12vdc system, the required current will be closer to 25 amps, once you take into concideration the power wasted by the amp in the form of heat. Check the fuse requirements of a quality 50 watt per channel amp and you will see what I mean.
You had better plan on adding significantly to your battery banks, along with a quality current monitoring system, to ensure you are not left in the dark after only an hour or two of listening.
