Watch how to make the box below:

When you want some clean sounding bass look no further than the Strato 12” subwoofers. Clean subwoofers deserve a clean box to play in. For the latest collaboration between CT Sounds and myself, Mark of CarAudioFabrication I wanted to build a box that would not only sound great, but would look sharp and integrate well into a vehicle.

To begin I started with a design that is available for download here on the CT Sounds website. I cut each of the pieces to spec following all of the dimensions that are noted in the design.

With all of the pieces cut I used my router to perform edge profiling, rounding over parts of the customized baffle as well as parts of the port for smooth airflow. Also note I made a window brace to keep the box structure nice and strong in order to handle the power of this subwoofer.

With all the pieces cut it was time to start assembly. I always start with assembling the back, bottom, and one side, I do this because this is a great way to verify the enclosure will definitely fit in the vehicle. Since it does in fact fit I proceed with the rest of the assembly of this dual subwoofer enclosure.

Once the box was assembled it was time to paint the front baffle and ported section of the enclosure. This will give a clean look and accent well with the carpet. Next I protect the painted areas with tape and apply upholstery glue and wrap the box in carpet. When using upholstery adhesive be sure to cover both surfaces, allow the glue to fully dry, and then begin wrapping. I always make sure to account for the carpet wrapping process in the build of the enclosure in order to plan where the seams of the carpet will be. In this case I use hard lines on the perimeter of the port and on the sides of the enclosure as guides for precisely cutting the carpet.

I concluded the box build with installing wiring and secured the subwoofer into the box. The box is now ready to be installed into a vehicle! Thanks for checking out this build!

This subwoofer box download was straight forward

I downloaded this well over a year ago, and built it out of oak, it sounds great and holds up to the abuse I put it through, although I went with other subs besides the strato at 4krms I have no complaints! Especially for a 5.00 download
