Im ready to pick up the sheet of MDF tomorrow, and my subs get here Monday/Tuesday. And my amp (IA 20.1) should be here by the end of next week if all goes as planned.

Anyways, I am not working with the biggest trunk and I have some questions about what would be the best/loudest.

Max Height: 14"
Max Depth: 16"
Max Length: 41"

1.) Subs back port back sub back : port location: Across the top [Kerfed]
2.) Subs back port back sub back : port location: All the way to the left/right of box [kerfed]
3.) Subs back port back sub back : port location: center of the box with 2 subs on each side [kerfed]
4.) Subs back port on side or front.
5.) Any options 1-4 but subs up

Pretty much im lookin to see what port varation and sub position would be best for this setup in a closed trunk where the seats don't fold down.

X2. In my experience with trunk cars, they're louder firing both the port and subs back... if you can completely seal off the trunk and fire into the cabin, that is ideal but probably not an option in this case.

this is the way I wanna go, but in terms of calculating the Lv (port length) of a port in the center of the box, I know 1 measurment goes from the middle of the port on the front all the way back almost to the port wall, but 1/2 the distance it is wide.. Kinda confusing, but since there are 2 port walls here where 1 goes to the left and the other goes to the right, do I just split the difference?

Use pool water.

Prime example of why not to inbreed.

can't go kerfed port in middle, i can go regular port in middle, but the port area would be 10in^2 less than recommended...
