the sd-2 isnt classified as a shallow mount but it is more shallow than the rest of the lines. What are the specs on the box?
And like boosted said, building a box yourself would have been better, its extremely easy
SD-2 is suppose to be shallow version of the SA line. Its not a true shallow mount but more shallow than most regular subs.
Box will be roughly .62 cubes in each champer so after displacement im looking to be right on with the requirements of that sundown specifies for this sub. Sealed.
I use to build boxes in highschool for local people, now with college/2 jobs i really dont have time or really place to do it anymore so for me i rather pay to have a box made, local shops didnt want to mess with it or wanted IMO WAY to much money to build one.
