TC Sounds/Eclipse Sub Box

[SoCaL081 10+ year member]

Recently got another 12" Eclipse titanium SW9122 but instead of a small sealed enclosure, I'm wanting to go with a ported box but dont know how exactly how big of a box to build nor the port tuning...Its going in a Jeep Grand Cherokee Laredo so I have quite a bit of room in the back. Ended up going with a Skar RP1200.1D amp to run the single 12in eclipse titanium but could use some help & advice. I attached the specs of the "12 Eclipse Titanium SW9122DVC sub & also what type of box I'd like to make but wood is also alot too and will probably need (2) sheets of MDF $40ea along with all the other stuff I need so should I even build one or find a decent prebuilt?

I think I can help you out here. I've designed for these woofers before, like your problem of trying to find box specs is always a problem with these subs.

I would totally do a custom.

IIRC, these subs like slightly smaller boxes. I have a 4th order saved for 2 of these for an SUV, anyways. I turned out really well.

I did this in 2015:

So just let me know. These subs are soft and work well in 4th orders. You see that Fs of 22 hz on that sub? That's really low for a 12, but that's part of an indicator that they would possibly like sealed. Just let me know, and I'll see if I can source any further t/s parameters to help understand the woofer and how it's going to act in different boxes.
