the JBL website should have all the info you're looking for. but if you're really not going to go there for some reason I will tell you that they are rated at 300w rms, and if you want to port them you will need, or in my opinion want a box that is around 2 cubic feet per driver and tune them low. Like 25 or lower low, its a shallow mount sub and was intended to be used in a small sealed box. I ported mine....it worked sorta but its an awful big box.
