need help with wiring subwoofers

[datexicanz]

i have two ulitmate kw1200 dual 3ohm subwoofers & i'm needing help wiring them so would i wire them in series or parallel to a Ds18 Candy-XXL1SL amp

Voice coils on each sub in parallel and then the subs in series for a 3 ohm load. I doubt that amp can handle less than one ohm but if I am wrong the subs could be run in parallel for a .75 ohm load.
