Box Design for FI Audio X12

[sbelew 10+ year member]

I had a fellow member on here a few months ago help me with a sealed box design for an FI Audio X12, 4 ohm sub with the BP Power Option, but I have lost all his emails and cannot remember his name.

The space I have to work with is 8"h x 32"w x 12-15"d It is going under the rear seat of an F150 Extended cab. I will be running it on 320 watts initially, but will soon be upgrading to 400 watts. I have the sub now, just need to build the box.

Thanks

I'm guessing your firing the sub down, correct?

yes that is correct. it will be under the passenger side of the rear seat, firing down. FI website says the box is to be be .6 to 1.1 cu. ft I think the other member, who is a fan of FI subs and recommended them to me, told me to go with about 1 cu ft, but as I said, I lost all that info.
