i have a fi bl 15 dual 2 with flatwind and cooling. it's going in a trailblazer; although i have a lot of room i dont want to use it all. i need some help deciding on the dimensions of my box and how i want it tuned. I want it to sound good but get really loud. i listen to all kinds of music if that matters. any help would be appreciated.

4 cubes @ 32 hz. What are the dimensions of your cargo area and how much do you really want to use?

it's about 3 ft. front the back seat to the rear wall and a little over 4 ft. wide. but 4 cubes @ 32 hz sounds good. thats what i was thinking about anyways

do you think a t10001bd will be good enough?

Yes.
