Default Round port for fi btl ufo 18

I just picked up my first 18. It's a fi btl ufo 18 and was going to do a 35w21t21d box for it and was wondering what would be a good amount of port for it. I was curious if anyone might have the specs for it. I can't seem to find them anywhere. Would two 6" aeros be enough or not quiet. Kinda working on limited space since it will be in the back of a extended cab. Will be running a hifonics brx2000.1 on it. Have big three and optima yellow top for electrical. Any info or advice would be greatly appreciated. Looking for a nice Dailey setup and was also wondering what tuning frequency the sub likes also. I don't have a pc so it's kinda hard for me to access Torres or winsd right now. Thanks for any help with it.

With the two 6" it would be 6.4 cubes. Not sure the displacement of the sub. Giving it .3 cubes as a rough estimate.

Ok thank you. I've wanted a 18 for a while now and this was only 200$ on my local cl so I jumped on it after some quick research. Just wanna do it right the first time.
