I have 2 12" Alpine Type R dual 4 ohm drivers and a MRD-M500 Amp and I cannot figure out the wiring at all, I have tried many different ways and nothing works!

I have tried this: ring.html?subs=2&impedance=DVC4x2

And I have also tried this:

And nothing seems to work, Both subs function fine by them selves, any suggestions would be awesome, Thanks.

you have a mono amp and two DVC subs.
bad combination.
what you actually need is a second MRD-M500
then wire the coils on each sub in parallel, and slap one sub on each amp.
you'll give wach 12" 500wRMS, and they'll absolutely pound.
I'd strongly advise a sealed box setup doing this, as you'll have a bit more than their rated power, and the added damping of the sealed boxes will help compensate, and prevent damage to the subs.
Also, while you'll lose maybe +3dB going from ported to sealed, you'll hit a lot deeper and more accurately without coloration or harmonics associated with porting an enclosure, and you'll get a lovely flat response down to about 9Hz.
