I have read a lot of post about people making boxes for this sub and I know that I got enough space for one (trail blazer). But the problem is I don't know how big of a box I need to make and what hz to tune it to. So if someone has this sub (which I know a lot of people do) could you help me out on making a sketch or a design or something that could help me out on building a box. Or is there someone that I could talk to that deals with makes boxes or makes the best boxes for this sub?

 
I will use it for daily driving, but of course I would like it to hit the hardest it can. I plan on later getting a sundown saz3000d but for Right now I have a us amp merlin md2d 1500 watts. And I really don't know what you are talking about when you said preferences, are you talking music wise?
