If you get 12s decent ones can handle 500 a piece easy boss over rates their stuff so at two ohms yor probably looking at 1000 watts if your lucky. Just wire the two subs in parallel and you'll be fine. I had two jls kicking at 1000 watts rms for sure because I has an infinity amp and that **** moved your stomach up and down after you would eat. I know a decent amount about car audio used to be all I was into lemme know if you have any other questions about anything or products
