would i be better off going with a 1.9cu. ft box, or a 3.27 cu. ft box?

3.27cubes Ported would be the best if u like more SPL than SQ, but those subs dont really have SQ, so why not port them

whoops, i forgot to mention that they were ported boxes...

also....if the box DOESNT have seperate chambers for each sub, does it increase your overall SPL? i was just reading something about it, and it says it increases it....

No...keep it in a single chamber, there are no effects that separate chambers in a ported box can have unless they are tuned diff.

For SPL purposes, the optimal box for a 1200Q is 4.9 - 5.5 cubic feet tuned to 44hz. This will give you about +10 db of efficiency @ 47hz (I have a screen print of the WINISD graph: http://www.geocities.com/spawn571ko/spl2.jpg). The efficiency will increase with higher tuning, but if you go much higher, it will be a "burpbox" and have absolutely zero SQ.

if i dont have seperate chambers, is that a problem?

Not at all, I don't recommend doing separate chambers for a ported box, there is absolutely no point...
