what would the difference be  in a dvc  and a svc  what the same power rating, would one have more spl or sq or what?

No difference at all in either.  Just a difference in total ohm load to the amp.  One should decide on SVC vs. DVC depending on these factors:  How many subs are there going to be?  What amp is being used, and what RMS power at what ohm rating? 

If the decision is, for example, to use two subs, and the amp chosen provides 500 watts at 2 ohms, then the two subs need to be wired together to form a 2 ohm load, and have a combined RMS of about 500 watts.  So two SVC 4 ohm subs would likely be chosen, and wired in parallel.

But if the amp will provide power at no less than 4ohms, e.g. a stereo amp bridged, then two SVC 4 ohm subs would not be suitable.  For this, two 4 ohm DVC subs might be used, so that each could be series-wired to 8 ohms, then the pair of subs can be parallel-wired to the amp for a 4 ohm load.

Often, some manufacturers offer the very same sub in a choice of 2 ohm DVC or 4 ohm DVC, or as a single voice coil, just to allow for the variables in wiring.  The power capabilities and performance of each remains the same.

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

im going to be using the Pioneer d class amp, and runing it at 2ohm 500watt

One sub = dvc 4 ohm - parallel wired

Two subs = svc 4 ohm - parallel wired

Four subs = dvc 4 ohm - series / parallel wired

Use the setup that stevdart stated above.

im going to be wiring 1 amp per sub.

so i need dvc subs and wire them in Parallel

The easiest way to think about it is this:

"The Amp is like a pair of eyes looking out, it can only see the resistance that you show it".

If your amp is looking for a 2 Ohm Load to get the maximum power out of it  ex. 500 watts @ 2 Ohms, then you would want to wire a DVC (4 Ohms / coil) in Parallel to show the amp 2 Ohms OR 2 SVC in parallel to show it 2 Ohms.

Here is the math:

Coil 1                      Coil 2

4              x                  4                              = 16

--------                      --------                      -------------                 = 2 Ohms

4              +                  4                              = 8

Hope this helps,

Dutch
