The chart here has provisions for only 4 woofers.  The following diagrams are for 3 woofers.  You can do this for each 3 woofers and then parallel the 2 sets of 3 for a 1.33 Ohm load or a 3 Ohm load.

Option 1 (series/parallel) = 2.67 ohm load
Voice coils wired in series, speakers wired in parallel
Recommended Amplifier: Stable at 2 or 1 ohm mono

Option 2 (parallel/series) = 6 ohm load
Voice coils wired in parallel, speakers wired in series
Recommended Amplifier: Stable at 4, 2, or 1 ohm mono

So I thank you should go with 4-12's or 4-15's which ever ones or get another amp just like it and strap them together for the 6-12's or 6-15's

Note if you do spl comps I will go with 4 subs unless you intend on being in a high class with the really loud vans/trucks 165db+

I really think he is going to need some different amplifiers if he is looking for 165+

not really i almost hit that with 4-12's and the new pa5500d at 1 ohm
it could happen. I am getting another one and strap them together and run them at 2 ohms. Amp gets a little hot somedays (great amp though)

Come on now!   165db with the mic in the port maybe!       If you doing a 165 on the dash or on the floor period that is enough to win most usaci classes Stock/Pro Stock/ mod ect ect.

Numbers in the port mean nothing.   If I wanted to stick the mic in the port I can do 170+ all day on the term-lab..150+ on the dash sealed for World record runs is a major accomplishment

The mic was on the passenger window (where it is metered) at 51hz tone. Music I hit 157 all day long. I just put this in about 4-5 months ago so I am waiting until next year to beat people. I don't care if you believe me or not I know what I hit on the term lab. I did go to about 6 last year with one re audio 15" xxx and hitting with music 143.9 but with bass tones hitting 151.6db in my van. I am not here to brag about my stuff just here to help people out. If you want to start something go somewhere else

Depends on the speakers but I would go for the 6-15's more surface on the speaker so more air movement.

How much effect does the vehicle have on your peak abilities? Like those vans that are striped, all the vibrating metal cuts the db level down no? Can you increase pressure by containment? Like a truck with a thick bed cover ported into a standard cab.

Will with the vans you have to put sound deadener before even starting this. From the back to my B piler, I have lots of sounding deadening. (roof,floor and walls and wish someone would make sound deadening for windows too). Everything still moves because of the air moving but nothing rattles. I have build some trucks that only the port was in the truck. (95 ford ranger with 6-18's in the bed and the port in the middle) Insanely loud. But he had a fiberglass lid reinforces with the second skin and expanding foam. Don't know what he hit but a way to a comp he rolled his truck.

Back to the first question? Stopping everything from vibration could increase your car/truck Db by 3 or more Db. Don't quote me on this for official Db numbers but just in all the years I have build and install I have see them numbers increase just by adding sounds deadening.

Hope I answer your question if not Let me know what you are asking about and maybe I can spend some light on it.

While you can do it a couple different ways?

You can face thing up and dynamat and foam in the truck to stop the body panels from flexing.

You can face them down for a stealth look.

you can make the rear seat go down and face them forward.

Every question and answer is up to how much work you want to do.

How much room?
Can You do it or have someone do it?
Do you want to do it?
