Hah! All I can say is that right now I'm 2ohm off the 3500 at 14+ volts steady and the amp get down. I really want to hear her at 1ohm. The 5500 is a monster amp and stronger at 2ohms, if you can afford it go for it I know I am in the future.
Oh yeah almost forgot I had the same feeling when I unboxed mine close to a year ago!
