I had the original Fox box for about six years, going strong and happy with it, with no complaints. I had been eyeing this Ram Elite box for some time, going back and forth as I wanted the internal air volume to match the specs of my subwoofers, so I finally pulled the trigger. Let me tell you, it was a game changer. I have the new Elite box powered by a Sundown Audio SIA-3500-watt amp with two 12" Deaf Bonce SA-272s and a 370-amp Mechman alternator to back it up, and man, this box hits hard. Deeper bass, louder, and the lows it produces really woke up my system and shakes everything. If you are planning on or even thinking about getting this box, do it; you will be very happy and pleased.
