Well I just came down to a world of confusion. I went to my truck, lifted my seat, saw my amp, got a little close and BAM it hit me in the face. 1200w .2 I have a 2 channel amp not a mono. I would have sworn by my life it was a mono

A couple things to concider here. Your amp is "rated" at (I would say grosly over-rated_ 840watts at 4ohms brigged. Your subs come in either 8 or 4ohm configs. Need to know which coils you have to better help. All-tho it is most likely over-rated, it is still most likely capable of putting out more RMS power than the subs are rated for (150 RMS ea/ 300 total).
You could port the box but it needs to be done in portion to the exisiting box volume and within the paramaters of the sub. Can be done, but alot goes into doing it to a already made box. Another option woud be to add additional baffels to the inside of the box to cut down on the volume of the sub chamber to get them close to the originals you had.
In any case the sound is going to be different because the subs are pointing in a different direction.
Edit: Looking back at the specs, your new box chambers don't fit in the specs for those subs in a vented enclosure (min 1.75 CU.ft., yours are 1.41 CU.ft.) I feel your best option is to try to take some volume away.

i was playing around with it and im thinking of making 2 more holes on the box for 2 10" audiobahn dvc 300w subs. im thinking of keeping the 2 c12s how they are and reverse mount those 2 10" audiobahns. cause im at 1.41 per chamber so putting that extra 10" in the chamber is gonna bring down the air space available for each sub cause theyre gonna be forced to share the air space. what do yall think of that? i know i sound crazy but i like trying new things

I've been hard at work all day. Sorry I didn't get back with you. Anyways, as you said earlier, you've got the SVC 8 ohm's? If you had the subs wired the same on the same amp, just different boxes, do some simple adjusting. The airspace is the reason why the volume "sounds" louder/different, and adjusting won't fix that completely but it probably calls for some regardless. Either way, you'll probably want to ditch those Comp's at some point or another. They aren't worth fooling with, IMO. Also, the idea with the extra subs isn't worth a go. Save your money and drop some subs in a box that is spec'd right.

its cool CCO5 i appreciate your help bro! & i do actually plan on getting good subs in the future but not right now. I think im gonna be crazy about it and go thru with what i had said earlier using my 4 subs in that box. Now lets see if that amp does it for me, i drew a diagram of the wiring to see if the wiring gets your guys approval 2 kicker c12 300w 8ohm and 2 audiobahn 10" 300w 4 ohm. and my amp terminals are in the wrong order but you get the point

It'll work, but I'm sure that it'll be "boom boom soup". I'm not going to type a full page in-depth description about this, BUT if I were you, I'd just stick with the Comp's and dial them in with what you've got. Save up, get a quality mono amp and a proper sub/box combo. I know you might like to try new ideas, because I'm the same way, but remember that every few dollars that you spend trying those "ideas", can fund a proper setup before you know it. If all else fails, play around with it and learn a few things.
