First ill start off saying that i fired the sub up, and i hated it. So i had to make sure that the sub was something i really wanted. Imade a 2 cube sealed for it that i absolutely loved. So now it's time for the project.
Frst, the problem.
Fitting this big bastard in a box, that is 3 inches smaller than the outer diameter of the sub
its 11 inches deep, But ill get to that later.
first i designed the box. its 3.2 cubes net with 34.5 inches of port area firing to the right tuned to 25 HZ.
then i added mdf rings on to the front. i used 2 rings on the front. one is a flush mount, and the other is a sub mount ring. i also cut the front baffle in 2 pieces so i could make everything fit.
Yes, that is a hole in the top of the box. This is back to the sub being 11 inches deep. all the way back to the motor structure would be hitting the top of the box without the hole cut......plus it looks better.
of course all the screws holing the mounting rings to the front/top of the box are countersunk. the reason it is 3/4 inch bigger on the bottom is because it screws into the bottom of the enclosure.- i also added weatherstripping to the sub mount ring, just to ensure an air tight seal between the sub and the screws.
You gotta know that Fiberglassing is involved. i cut the rings at the bottom, to fit with the bottom of the box, because i needed to squeeze out every inch. A dodge neon trunk isnt very big.
