I never heard of wetsounds til I saw them earlier. I need to get up around 1600-2000 watts total. Not real confident that can happen
You dont need anywhere near that power. 100 or so each on the sv165, 200 each on the sv200 and about 50 on the st35. You never mentioned horns on the front, otherwise a JL 800/8 in bag( should fit fine) will have plenty for all of it. You have efficient PA speakers. Don't need a ton of power to make them sound good.
The sv 6.5 are 400 a set and I'll have 4. 200.1 is 500 set then hertz said 150 or so to st35. No horn up front until all gets installed. 1 set of horns may be enough
You're looking at your numbers incorrectly. Have you hooked any of this up? I think Slyes recommendation is on point, especially if you want your amps in the fairing. If you want those kinda high numbers there's no way you are doing it with little Amps in the fairing. You gotta use bag amps.
I talked to at least 5 people and every one told me the 800 diamond I have isn't enough for 2 sets of sv165 and a set of 200.1 and st35. How much more do I need
Add a micro 4 bridged or a dds4 bridged for the 200.1. Run the sv in parallel of front 2 channels of 800.4 and add some horns for front and parallel with the st 35. Best to match the 35 but the st25 does have same power handling.
