i have two 4 ohm subs wired in parallel to a 2 ohm load. If each of the 4 ohm subs has an rms of 150w how much wattage do i need the amp to rms at?

I first thought because they are wired in parallel that i needed the rms to match the rms times number of subs (150x2=300) but now im thinking i only need the amp to put out 150 rms on a 2 ohm load.

I dont know so thats y im asking.
