There's a bunch of information missing... This question cannot be safely answered with the information you have provided.
What is the rated power output capacity of the Amplifier at 8 Ohms? What is it's rated output at 4 Ohms? Your problem, is can it do 2 Ohms, stabily?
The next problem you have is underdriving your speakers, as you've now got 4800 watts of power, this has the potential to burn out the motors... Another problem... You're not specifying if that 1200 Watts is Peak, RMS, or Peak-to-Peak (Max)...
On top of this... how big is the box? What are the Thiele-Small specifications of the driver? If you take a really efficient driver and put it in too small of a box, you'll cripple it's bass output capabilities... where as if you put a not so efficient driver in a large box, you likely end up ripping the surrounds off the frame. Is it a sealed box, or ported (4th order bandpass, or something similar)? If so what are the dimensions of the existing box? Or are these new boxes you are building?
------------
To clarify from a prior answer about speaker wiring... ;)
When you run series you do not multiply by 2, you add...
Hence... four 4 Ohm drivers in Series does not become, sheesh, how would you even apply that?? Lol... Uhhhh...
Properly... it would be 4+4+4+4=16 Ohms... when you run them parallel, you end up with 1/(1/4+1/4+1/4+1/4)=0 Ohms... you'd blow your amp in a second... so you could run series/parallel, for instance 2 row, with 2 speakers, so you would end up with 4+4=8, 4+4=8, the 1/(1/8+1/8)=4 ohms... if you need 8 ohms, you'll need to run 4 of those drivers, in two independent pairs of two in series...
So cabinet 1 would consits of two drivers, and cabinet 2 would consist of two drivers, with each cabinet independently wired series... so when the amplifier, provided it's stereo sees each channels impedance load on it's output as 8 ohms...

you need to match the ohm of the speakers to the receiver. you can do this by getting 8ohm speakers or you can run 2 4ohm wired in series. Remember when wiring in parallel Divide your ohm by 2 and in series multiply by 2. when you try to run lower ohms you will burn up your amp
