You are gaining half a cube from reverse mounting the subs so the 1.5 cubes left are very little difference so give the old box a try, you have nothing to lose.

 

Pick a worthy amp and feed it with a worthy electrical, that is actually what is going to make a difference.

Gotcha. I have a 400 amp mechman alt with 3 Oddesy ODXAGM3478 with 3 runs of 0/2 pure ofc welding wire.  I'll be getting a Soundcubed Q-1 6000.1.  It will do 6000 plus rms at 1 ohm.  Box raise may be around 1.33 ohm, but no concern there.  So I should be good.

Let us know how it went, you should gain about 3dB for doubling power, see if that is loud enough for you.
