I just bought two 12 inch 2ohm dual voice coil MB Quart PWE 302's. I was wondering if there was any way to wire them to a mono amp so they stay at 2ohms and not drop down to 1 ohm or a 1/2 ohm. Thanks.

Yes.  Basically you have a total of four 2-ohm loads.  The following series/parallel combination will present a single 2-ohm load to your amp:

Wire the voice coils of the first subwoofer in series.  This is a 4-ohm load.  Wire the voice coils of the second subwoofer in series.  This is another 4 ohm load.  Wire the two 4-ohm loads in parallel.  This is a total load of 2-ohms.  I made a cheezy diagram so you can see what I mean:

I hope this helps.  Remember that resistors in series add, and resistors in parallel combine by: RTOTAL = 1 / ( 1 / R1 + 1 / R2 + 1 / R3 + .....)

God Bless!
