Need help with Fi ssd big box.

[Kingyperson]

New guy here!

I am buying a 1993 dodge minivan and taking out the back seat to put in a box. As of this point and time I have one Fi ssd and plan on purchasing another around tax time. Furthermore I intend to purchase two more after replacing the alternator/adding another (this is all a lofty goal, I understand) This is what I have so far. By the looks of things I might be able to get away with it but I am worried about the port area. This will be a "daily driver" with a serious lean on SPL. The 47 inches is the best I can do side to side in the wheel wells and I would like to keep the box under the windowline at 18 inches. I do have more room to grow out towards the drivers seat if need be. Thanks for taking the time to look! Any info at all or opinions are appreciated.

This is an update. I took it out four more inches and changed from an L port to reduce to amount of MDF the sound has to come in contact with. Please let me know what yall think of this build. I will be starting box construction by next month. I would greatly appreciate any input.

first off, never use RE calculator again, its the worst out there.

use this instead

Be sure to model your sub on winisd and see how it would perform at given specs too before you decide to build it
