Yes, 1 for main cranking and 2 in parallel for the house/stereo bank.

When wiring 2 batteries together, they become 1. Ideally, you would want them both to be the same size, type and age. If this is a new boat, then I would not hesitate to just wire in that 2nd house battery to the existing hose battery. If the boat happens to come with 2 cranking batteries, which is very common for an OEM setup, then I would swap the cranking on the house side, for 2 deep-cycles.

DSP is no joke. I have it in my RV for radically improved sound quality for those long drives. All future cars and trucks of mine will be DSP equipped.
DSP may be used very differently in an open boat versus a closed vehicle cabin. However, DSP can be just as valuable in a boat as in a vehicle. Imagine phase correction on multi-pair tower speakers that are staggered on a forward leaning tower or staggered mounting on front and rear tower tubes. Or, DSP can correct the phase between the tower speakers and subwoofer at a focal point just behind the transom.
Earmark Marine and Earmark Car Audio does a ton of DSP. And Wetsounds added DSP to their newest demo boat.
The one cautionary note is that there are many, many complexities related to phase correction other than the distance differential between drivers alone. And there is much more to equalization beyond simply creating a ruler flat response. It's still a job best left to the pros. But there is no doubt that DSP is a game changer.

Hey Mike,
So if the boat comes with (4) 4ohm speakers then I would wire each side in parallel to represent a 2ohm load at the amp? That way all 4 speakers are 100watts each? The 2 bow speakers would be 4ohm as well but just those pair off the other 400.2 amp to show a 4ohm load at 100watts each right?
I think to keep it to (4) amps I'm thinking of doing (2) 800.5s for the tower & do (2) KM10s under the dash & have an extra sub channel for future? The KM8s would still be getting 200watts each right?2015 Mondo

Yes, the KXM400.2 would deliver 100W rms x 2 @ 4 ohm, so 100W to each speaker with one pair. 200W rms x 2 @ 2 ohm when a pair is wired in parallel to each chnl. They split the 200 and net 100W.
Two KXM800.4 would drive 2 pair of the KM8 @ 200W rms each when bridged into 3 chnl mode.

Ive done it on a number of our Kicker Promo boats, like the one you saw, because I know how the system will be used. Its a lot to ask of any typical amp, but I have confidence in the Kicker product. As the design takes shape Phil White, Kicker's marine guy, is part of the planning.
With proper install practices, good tuning and battery voltage management, I do not foresee an issue in your plan.
