Two Kicker 12'' CVRs, Orion 3000

I just purchased two 12" 4ohm DVC Kicker CompVR subs and I asked my dealer what the best way to wire them is and he said the parallel/parallel wiring configuration for a 1ohm load would be the best. At the moment I have an Orion 3000 amp (I can't find this amp anywhere online...I believe its a 600.2 rms, but it says "Max Power 600 watts" on the amp itself so it might be 300.2 rms) and don't have the funds to buy a new amp. If it is a 600.2 rms amp running at 2ohms will the amp overload the subs? Would I be better off wiring the subs in a 4ohm load and saving up? If it is a 300.2 running on 2ohms is there enough power? I'm only using one of the channels so would bridging the amp be better? Thanks, Austin

you can wire the amp either 2 ohm stereo or 4 ohm mono
