That all depends what leaving it as is means. We don't know how you have it currently wired. If you have the amp bridged and all of the sub + connected straight to the amp - DON'T Keep that running! That is a 1 ohm load which is detrimental to a 2 ohm stereo amp.

If you mean keep your equipment. Yes, it will work fine.
But now you have to choose what set up you want, stereo or bridged. Both will net the same end power.

If you do stereo, connect both + of one sub to the L+ on the amp, and the - of the same sub to the L- of the amp. Do the same with the other sub to the right channel. That will give you 2 ohm stereo.

If you go bridged, you go from the bridged + on amp to coil#1 +. Then from coil#1 - you go to coil #2 +. From coil#2 - back to bridged - on the amp. Repeat procedure with the second sub.

My personal preference is running stereo because then you avoid wiring the speakers in series.

What amp is that?
