2 sundown SA-10 or 1 x12?

I’m having to change my system up because one of my subs died. For an SPL setup should I go with a pair of Sundown SA-10s or one sundown x12? Either way I’ll be powering at 1100 watts rms since I don’t want to put too much excessive power on my alternator and both setups will be rated at 1500. Was wondering which would be best for loud bass and feel in my car.
