The amp is listed at 4 ohm stable.

If the subs are each 4 ohm, you would have to run them in series and would be using less power.

I would search for an amp that is two ohm stable and near the limits of the subs, or another sub box that has two eight ohm subs and keep that same amp.

Perhaps I am missing something obvious, but that is what I would say based on what I see.
