So i decided i was a little bored and decided i would teach myself how to make a sub box. plus i was sick and tired of my old one and couldnt see paying somebody else to make a box for me. so what better way to save money and make it how "I" wanted. it was a great learning experience except i couldnt figure out the math part so i just guestimated how big it should be. so if somebody can help me out with the math formulas it would be great. the part where the sub is, is 20" long 12" tall and 12" wide. its fully sealed and to me i think it sounds pretty good. sounds alot better than my old box that was ported anyways.

sorry everything is uber dirty but i dont have a vacuum

 

the box looks good but it looks a little big for a single sealed sub do you know the model number on the sub you could probably get away with a ported box and probably be smaller than that one

 

nice and a lil vacuuming would help

 

that thing is sealed?!?!?!?!

damn thats huge.

nice and ugly.....

 

say goodbye to putting stuff in your trunk... that thing is huge!

 

The box is only 1.18cuft (assuming you used 3/4" MDF) and the dimensions really are 20 x 12 x 12. After sub displacement it probably close to a solid 1cuft which is usually good for most 12"s.

Box look nice, just clean things up a little lol. Having a trunk is overrated anyway. My box takes up just as much space as that one.
