1 Alpine type r 12' or 2 mtx terminators 12'?

i recently had 2 mtx terminators in my car tht can as a package with an amp unfortunately the amp came kinda broken so i had to send them back but they sounded good when i made the amp work. My question is should i get the same setup or 1 alpine 12 with mrp500 amp in sealed box. WHich will be louder and better for lows and so on. All answers are welcome
