How many watts should I run to 2 audiobahn aw1200x 12's subs?

What amp should it be i am thinking of visonik or pyramid I dont have more than 200$ to spend and would like to spend less!

And if you no a better hitting sub for the money please mention it and it needs to have 2 subs for not over 200 but i am shopping on ebay!

Oh how many channels do you need for 2 12's I dont understand if you need 2 4 1 what I would like to run low ohms like 2 or something so what do I use?

Thanks guys!
