Have you done the calculations rather your black box matches the requirements of your driver? Simply putting the 10" or 12" driver into any box will have sound. However, in order to optimise the performance of your speaker driver, the volume of the "box" must be calculated to the specifications of the driver.
Pls reder to the below information.

" Calculating Speaker Enclosure Volume
As you already know, for speakers (especially woofers) to work properly, they must be in the proper size enclosure. The manufacturer can give you the required enclosure volume but can't give the exact dimensions of an enclosure that will work in all vehicles. So that you can build an enclosure of the proper size for your vehicle, this page will explain how you calculate the total volume of the enclosure.
Magic number:
OK... It's not magic but the number is 1728. If you forget it, just remember that the number is 12 inches * 12 inches * 12 inches. 12*12*12=1728.
Square or Rectangular Enclosures:
These boxes are the easiest to calculate the internal volume. You simply measure the height, width and depth (in inches), multiply them together and then divide that number by 1728. If the box has internal measurements of 6" high*18" wide*12" deep then the volume of the box is 1296/1728=.75 ft^3. The diagram below shows how you would measure the dimensions of the box.
