x2 a fully loaded BL should handle 1650 RMS, but im not positive i dont have any personal experience. and if you need a sub and amp and box, its almost impossible to also get a RF 360 under 700 total.
sorry sorry i was doing two things at once, i didnt mean that. My bad. I believe they say that you should get the P chamfer at the bare minimum, but i would recommend the whole cooling option if you ever plan on running more than rated RMS to them.
