You are both right. 600-900rms on a mag will get loud. We have had customers run the new mags at 2000rms a piece in spl competition before. For a daily driver we have lots of people running them at around 1500rms at 1 ohm and they are very loud. If you have a newer mag then it should be able to handle about twice the amount of power that hifonics amp is putting out without any problems. (maybe slightly less than twice). I can't speak for the older models since I have never dealt with them. But you should be very happy with the output you are getting in that enclosure.no //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
anything from 600-900rms with that box will hit nicely.
