DCON-12 S4 Box question

[depejohnson 0]

My son is looking at buying a DCON-12 S4 for his car. He will have a Alpine MRP-M500 pushing the DCON. We want to build a ported box for the DCON. SSA says optimal ported box is 2.25 cu.ft tuned to 28-33 hz. I tried downloading the box design from SSA. I can get the google sketch picture, but not the other file. Can someone help me with the box dimensions?

I am confused as to which file you need. Did you try downloading it again?

When I download the file there are 2 seperate files. Design and SKP. The SKP opens in Google sketch. The other file opens in word and is unreadable.

I attached the pictures for you.
