Hey.. I wasn wondering..
do i HAVE to have DVC subs to beable to wire my subs in a parrallel?
couldnt I just double up the cables on the posts?

You need more than one voice coil to run subs in parallel, but not necessarily a DVC sub. 1 DVC sub = 2 voice coils, 2 SVC subs = 2 voice coils.
To run a sub in "parallel", the positive terminal from the amp runs to all the positive terminals on the subs, and the negative terminal from the amp runs to all the negative terminals on the subs. This divides the resistance between the subs.
You can also run the subs in "series" aka "daisy chain" by linking the pos from the amp to the pos on the first sub, and then the neg on that sub to the pos on the next sub, and then the neg on that sub to the neg on the amp. Running in series multiplies the resistance of the subs.
As for resistance, two 4 ohm subs in parallel would create a 2 ohm load, while two 4 ohm subs in series would create an 8 ohm load. The lower the ohm number, the more power the amp can put out.
Let me know what kind of amp you will be running and what subs you will be running and I can let you know the best way to run the subs.

I'll be running
hifonics: Son of boltar (500watts)
150x2 @ 4ohms
2 Channel amp
2 Kenwood "tornado" style 10 inch subs...
forget the exact code number.. but its something something 2505... the updated version of the more popular blue faced kenwood sub.. which was something something 2503
max rms is 150 @ 4 ohms on the subs
I think I'm gonna go with my basic plan of just wiring it as two speakers.. keeping the 4 ohm impedance..friends with hifnoics amps say they are the best at 4 ohms... but I'm open for ideas...

If those are the subs I am thinking of, you would probably be better off running them on two different channels like you said. I'm not sure if they could handle the power given out by that amp if you ran them parallel at 2ohms. One thing you might want to look into is getting 2-8ohm subs. That way, you could bridge the amp and run the subs in series. That would give you a 4 ohm load, and you would be getting the most out of your amp.
