3 cvr 12 kicker 2 ohm dual voice coil

i did see that if you ran all three in series it would be 12 ohms and they recommended 1 2 or 4 ohm amp.  does that sound possible

At 12 ohms, you will get almost no power out of the amp.  It is stable to run at 4 ohms bridged, or 2 ohms stereo.  The only way you really have to run all three would be at 3 bridged or 12 bridged.  3 ohms is a little much of a load in my opinion, but kicker builds a pretty tough amp and would likely handle it.

Your best bet, as noted before, is to put two in a good box, run at 4 ohms stereo.  This will likely be louder than the three in any configuration with that amp.  Other option get an amp that is one ohm stable in the 1000 watt range.
