I have 2 MA12D4 subs, 4ohm DVC. On each sub there is a total of 8 terminals 2 neg across from 2 neg and 2 pos across from 2 pos. What would be the best wya to wire these and would i be wiring all of the 8 terminals? This picture shows what im talking about and if anybody can edit the pic and help me figure this out that would be great.

You have four terminals, not eight. Each terminal has two inputs for ease of wiring.

Here's a pic I drew up a couple years ago. If you're going for a 1 ohm impedance, this shows how it's done:
Look at the voice coil on the left sub labeled "voice coil one". I put a block around the two sets of input posts to make it simpler to see that although there are two sets of posts, it is still just one voice coil. The two positives are connected together (internally); the two negatives are connected together likewise.
The result of the above wiring is: coils parallel / subs parallel. The extra terminal inputs are used to connect a voice coil to another voice coil without having to put two wires onto one terminal post. You can see here that not all inputs have to be used, but that every coil is connected.

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