Thanks for the welcome. For the short time I have browsed this site it seems there is a lot of very useful information to be read. I cannot wait to gather up the items I am missing and start the newest build. I am always up for trying out new gear. Which is probably why I have been through so many different companies over the past couple years. I have used Audiobahn, Memphis, Eclipse, Oz audio, JL Audio, and Alpine for subs. I recently was turned onto Fi audio after talking to a few forum members from another audio forum I am on. I spent about a month or so debating on which sub to choose. I was looking at either a 12" Fi BL or an 12" Audio Que Hdc3. After having both modeled out for me it seems as if the Fi BL is the better choice. Should play lower then the hdc3 and the quality seems to be much better.
