When I bought my BTL N2 I was afraid of the "sound quality", after using Xcons, and Icons. But all I can say is that they sound really good and can play all the notes quite well. Finally I was not disappointed , in no way. I love the light weight and the sound of that sub. It's not an Xcon, I find it less flat, but it's still musical, not like a Soundstream XXX (we can buy them locally) or other purely spl subs. In the 350Z, it can be a good choice with that amp : just turn the gain down a bit, the sub don't need that much power.
