Here's my setup. Its in my boat btw...
I have a Mono 1 ohm stable amp. I have 2 DVC L5 (older) solobaric 10's. I think they are either 2 or 8 ohm, depending on the way they are wired.
The others are 2 svc soundstream 10's that are marine subs if that matters...
What I was thinking was wire the DVC's @ 8 ohms and the SVC's @ 2, but I'm not sure how to connect them at the amp...?
If someone can please give me a idea on how to wire them to get the most power that would be great!
TIA
Alan

The 2 ohm coil will be getting four times the power as the 8 ohm coil.

Wire the DVC's parallel for 2 ohms, per. Treat them as 2 ohm woofers, forget completely that they are DVC woofers.
Now, it's easy... You have 4 SVC woofers, rated 2 ohms each. Wire 'em however's clever. Use the woofer wiring calculator and plug in the numbers you need, again, treating them ALL AS SVC 2 OHM WOOFERS...
(The configurator doesn't offer a four 2-ohm woofer setup...) Your options will be:
Series - 8 ohms mono, or 4 ohms per channel on a stereo, bridged amp
Series/Parallel - 2 ohms mono, or 1 ohm per channel on a stereo bridged amp
Parallel - .5 ohms mono, or .25 ohms per channel on a stereo bridged amp
What amp will you be using? Without amp information, I can only guess the maximum power option, but the most universal option I see would be the series/parallel wiring option. This will provide you with (generally) the most power at the safest impedance, but that phrase WILL depend on the amp you have. All 4 woofers will receive the same amount of power, but that DOESN'T mean they will have the same output. The efficiencies of the drivers will be different, and the enclosure requirements will be different, as well. DO NOT try to put them all in a single, common enclosure. THAT will provide you a bad result.

Nice breakdown haemphyst... well spoken. A these crossroads, what way will you go? Add amps... optimize both pairs independently. Bumpin on the lake will be worth it.  ------------- This is what I do for FUN!

The amp is a mono block 1 ohm stable hifonics bxi2006D.
Looks like I forgot to say that the SVC subs are 4 ohm not 2 ohm. So to recap I have 2 DVC (2 or 8 ohm subs) and 2 SVC 4 ohm subs.
The boxes are built and the DVC and the SVC subs are in two different boxes.
So how do I wire them....The way I was thinking I should have a 1.5 ohm load if I wire the DVC to get 8 ohms and the SVC to get 2 ohms, right?

You can't do that. Only use one voice coil from the DVC woofers. Forget the second coil, and connect all woofers as if you have four 4-ohm SVC woofers. And before you ask, yes, it is PERFECTLY safe to do so, as well...
Parallel will be a 1-ohm load, and you'll be sitting pretty.
The ONLY drawback will be the reduction of power handling by the DVC woofers, by about 25%.
