mtx 9500

I purchased 2-12" dual 4 ohm MTX 9500s, can anyone suggest what SPECIFIC amp(s) I should run? Or anyone selling the amp(s) that I will need ?

I just wanted to know if is potentially harmful or will even work if I wire a single 4ohm sub with a dual 4ohm. Also, what load would this maintain if it isn't frowned upon. For reference they are MTX 9500's. Thanks In Advance
