re audio se subs, amp and box

I was looking at the RE Audio SE either 12's or 15's to put in the back of a 94 Volvo wagon and had a couple questions on them and an Amp i found.

The specs say the subs have 600 watts Rms each but i've heard they handle more, so i found an Audiobahn A1300HCT Amp for pretty cheap, new, with 1200 watts Rms at 1 ohm and was wondering if i could hook up 2 subs (dual voice coils) at dual 4 ohms to an amp at 1 ohm to get the desired power. if i could, could you explain how and if not give me some ideas as to how i could get the desired power as i am on a budget.

Also I have room for a 45" x 18" x 18" box in the back to hold the two subs and was wondering if approx 4 cu ft (per sub) would be too much or too little for a ported box. (i would be building the box myself). I have installed some stereos and speakers before but just new to the subwoofers. Any information would be helpful. Thank you

Ok thank you, I actually did find the sub configurer so....

Just a slight correction, the box is 45" x 18" x 18" which translates to about 8 cu ft. So i would be making a ported box, how would i go about making a port. I know there are port calculators and other calculators but i'm kinda new to this and dont fully understand those. is there like a rule of thumb for making ports?

And if i were to use a different amp, what does anyone suggest? it would need around 1200-1600 watts Rms at 1 ohm and around $200-250 since i cant spend too much. Thanks for the quick responses, Im learning a lot.

That Amp looks good, and its not too expensive. I also saw the MA Audio HK1998 1200w Rms for 210, but i dont know about MA Audio, any suggestions? I would really like a ported box, however a sealed would be a LOT easier to construct. The subs seem loud enough that i dont think it will make too much of a difference and the SQ will be better with a sealed.
