First off, thanks Mike for selling me your sub and your styrofoam trunk floor pieces to make this happen. I did not use any of your mounts or anything. I don't know if the NISMO is different but everything fit PERFECTLY and was very snug and won't move or rattle. The sub provides a decent amount of bass. Equivalent to a high powered system that would come in a higher end system in a stock vehicle these days. Nothing big. It's just a simple good amount of bass that is clear and makes the whole system balanced. Though at times I wish it had more juice to it. But seeing that it is this small, I couldn't ask for more.
If its not showing, heres the link.
