DC Level 3 10 box questions

[brocken]

Howdy all, it's the noobest noobie.

I just purchased a Level 3 10 with level 4 coils and extra spider.

This is going in a 2010 F150 supercrew and there's a premade box that has 1.25 cuft. If I understand the specs correctly, that's an optimum volume for this sub for ported?

I was hoping I can use polyfil to compensate for the driver's volume?

My goal is more SQ than all out output. Would I be better with the 1 cuft box volume ported?

Also, with either size box can I get a recommendation on port diameter and length?

I tried modeling the sub in Winisd but must have entered something wrong. I got a really high volume for the box, like 50 something liters.

Thanks!

is this is the wrong spot?
