I just bought a new kenwood class-D 1800watt mono 1 channel amp which is 1ohm stable, how should i wire my dual voice coil 4ohm kicker cvr 12''s? Im not to good with ohms and the wiring of the speakers with parellel and series, help would be much appreciated, thanks

If it is a Kenwood Kac 9105d it factory specs say it is not 1 ohm stable.
You can see how to do it here http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=2&I=42
How you wire it depends on how hard you want drive your amp. If your woofer runs 4ohm per coil I would wile it in series (amp +to sub +1 sub -1to sub +2 amp - to sub -2) then run it for a week and see if it has enough power. the lower your Impedance (the resistance load on the amp) the harder your amp works and more THD (noise) is produced. (Dclass amps aren't know for being clean to begin with) configured like this your amp will see 8ohms and sound the clean east. if this turns out to be not enough power wire it in parallel and double the output. wire amp + to sub +1 and +2 then amp - to sub -1 and -2.
A word to the wise... start with your volume very low and work up slowly most speakers will puk up the voice coil before the amp starts to get warmed up. you would hate to have to buy a new sub.
Have fun
