I see that three 4ohm DVC subs can be wired at 2.67ohms and three 2ohm DVC subs at 1.33ohms, but can two 12" 2ohm DVC Kicker Solobaric and one 12" 4ohm DVC Kicker VR sub be wired to a 1ohm load?

Nope, cannot be done. The most balanced way to wire all 3 subs is each 2 ohm DVC (Solo's) is wired in series for a net 4 ohm per each. Then, your 4+4 Comp VR coils in parallel for a net 4 ohms. Now, all subs in parallel = 1.33 ohms.
That's your best fit and all subs get the same power. (4// 4 // 4 = 1.33 ohms) The net equivelent resistance in this calculation = 1.33 ohms, which is your best option. All subs get the same power each.
If you wired all coils in parallel, (1 // 1 // 4 ) your net load is 0.4 ohms.
That value is too low for all but a few High Current (HC) amplifiers. HC amps waste a lot of power to heat as well. Not a great option and very expensive too.
Sorry, the only way to get a net 1 ohm load, (with 3 subs) would be to use three, 3 ohm subs (like JL's W7) all in parallel. (3 // 3 // 3// = 1 ohm)
If you wanted a 1 ohm load with just 2 subs, they'd have to be 4 ohm DVC's. (4 // 4 // 4 // 4 = 1 ohm) as well.
Got all that?

Yea makes sense. I just thought if I wired the 4ohm sub in parallel I would net 2ohms for 4//4//2.
I am thinking about dumping the 12" VR from my set-up since my KX1200.1 is probably a goner, and going with the new Kicker ZX1000.1 since it pushes 1000 Watts RMS @ 2ohms. If not, I'll probably buy another 12" 2ohm DVC solobaric and KX1200.1 and run those in series then parallel for 1.34ohms. What do you think is my best option if my current amp is fried? I really have no idea how the new kicker amps compare to the old ones, and if I'll get a better sound at 2ohms with identical subs.

tell me if my math is off, been a long day at work today....
Wire the 2 ohm solo's coils in series, 4 ohms each
Now wire those two in parallel, 2 ohms out
wire the 12", 4ohm dvc VR in series to get 2 ohms out of it.
put the net 2ohm of the solo's, and the net 2 ohm of the VR's in parallel to get............1 ohm?

4 // 4 = 2 ohms // 2 =1 There's the net 1 ohm. However, the Solo's are going to share 50% of the net power. The Comp VR will get 50% of the rest. Meaning, say we have 1,000 watts available @ 1 ohm. Each Solo will get 250 watts and the VR gets 500 watts. Not the best way to use an amp with 2 strong Solo's. A 2 ohm amp and just the Solo's being fed well, are a very good option.
Ohhhhh, can't see the forest from the trees here huh Ol' Swez?
I forgot to factor in the Comp VR was a 4+4 DVC. Yes, I was a bit snoozin there BR... sorry for the confusion and TY ttocs for waking me up again.

Thanks guys. I guess the 1ohm idea is crap since the VR is getting most of the power. I guess if my amp is fried I will get the ZX1000.1 and run my two solobarics.

Sounds like a very good plan in the making now. If you'd like to feed those 2 brute subs fully, the L5's can handle 600 RMS each. The L7's can manage 750 RMS each. More than enough power for most amps to deliver.
The right amp and a well designed enclosure, will allow these pups to push out some serious bass SPL.
