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

do u think i can use this set up on one of the amp terminals (+ -)  and the same setup with the other sub on the other set of terminals. would that create a 2 or 4 ohm load??

What you're proposing to do is create a 2 ohm stereo load.  Electrically, this is no different than the 4 ohms bridged diagram that dwarren posted. 
My ex once told me I have a perfect face for radio.

ooo ok i wasnt sure so i was just making sure im still new to all this.... so ur saying that mine is 2 ohm stero and his is 4 ohms bridge?? does that create the same amount of power or no?

Bottom line is this:

When you chose the combination amplifier / subwoofers, you already figured power requirements and impedance load you wanted to put on the amp.

Getting DVC's instead of SVC's threw you into a world of doodie.  Fun with fleabay.

Return them and get the right subs.

EDIT:  haha, the word "doodie" comes up now...

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

OK... Here's the BRUTAL truth:

1 ohm (all in parallel) or 4 ohm (series/parallel). You already mentioned that your amp is a mono amp. This means ONE channel. You could have 800 speaker terminals on the amplifier and it will still be a mono amp.
No matter HOW or WHERE you connect the woofers you got, you can ONLY get a 1 ohm (unsafe load) or a 4 ohm load (perfectly usable) on the amplifier. My STRONG suggestion (already posted on the first page): wire the woofers to 8 ohms (series) then parallel wire the woofers to the amp for a 4 ohm load. You WILL NOT notice the difference in power produced, I promise you this right now. You are looking at LESS than 2dB max output difference (3dB is noticeable) between a 4 ohm load and a 2 ohm load. Install your gear, connect the things for a 4 ohm load, and get on with your life... difference between dvc and svc? - Page 2 -- posted image.
Your amp sounds like a cheapie anyway, and it will THANK you for providing it with a 4 ohm load by running cooler, with lower distortion and better damping, anyway. Now, if it is REALLY worth your time and energy, contact your seller, pay shipping back to him, pay shipping again back to you, waste weeks of your time, your energy, your money... 4 ohms is sounding better and better to me already.

but by not using one voice coil wont that mess the sub up??? i mean i dont wanna break anything or blow it up

You wont. On the top of the front of the Car Audio Forums page is a sticky regarding running one coice coil on a DVC woofer. Good read. Check it out.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

hey thanks for ur guys advice its really helping me but i have one more question if i ran the subs in a series/parrelle wont i have to drill holes in the middle of the sub box (bc i have a divider between the 2 subs) in order to get the subs hooked to each other??

i was thinking bout sending them back but by the time i noticed they were dvc... i was so happy the came i didnt read the box ... i already had the subs out un rapped and sitting on my table so i didnt think they would take them back anyways

You know you have to drill the holes to get a wire from one chamber to the other.  Put the wires through and label each end of the wires.  Seal the holes with caulk.  Now if you pull the subs out of the box for a changeover in the future you will know how to use those wires more easily.  I use black 16 ga. primary wire for all the wiring but I use colored electrical tape near the ends to show how they should be used.  For instance, a series connector wire would have red tape on one end and black tape on the other.  You know what I mean.

alright thats what i figured i just wanted to make sure before i go drilling the box but im either going to do that or im going to try to just hook up one coil and wire them to creat a 2 ohm load and see which sounds the best to me
