ok i designed a little truck box and i designed it with 1.4 ft^3. and ill make this, seal it up good, stuff bout a pound of polyfill, and carpet it up nice. i figure ill finish it up wit about 30-35 bucks? hopefully. and later on if i need to ill build another one. but i dont have my card for my phone so i cant take a pic. but it is 23.5in wide, bottom is 10in, tope is 5in, and it is 20in tall. and the whole for the sub is going to be as low as possible because i read on a website the lower the better and it will also be located as far to the right ass possible too.
