Ya that's too much. I would personally tune lower. Daily, I typically wouldn't go over 16 in^2 per cube but there is some situations where you would want to. My 2 18's box has 12.3 in^2 per cube. How much power are you running?

But I get em cheaper then a I can get a pair of Evils lol.
I have ran a few different subs and boxes tuned as low as 28 hz, the only thing I didn't like was I didn't get a very good bandwidth at all when tuned at 38 hz. Even with the current box I have which is tuned to 34 hz I peak at around 28 hz on the meter, this is the second box that I have tuned to 34 hz and peaked lower then 30 hz. I am not really chasing numbers but I do listen to a big variety of music. I adjusted my calculations and got the port area down to 14.39 sq in/cube and maintained the 35.32 hz. If I am doing something wrong to get a peak at much lower then my tuned frequency please let me know, I am pretty new to the design process.
Appreciate the help Buck, I know you have designed a box or two in your day.

I honestly forget. He was a dude I met at our local vape shop.

I think alot of folks use way too much port area for music systems... I suggested 12 in^2 per cube for a local guy running 6 of the new X-12 v.2 subs in a wall -- results are ~159 dB @ 37 Hz withone window down / 158 dB sealed on the dash with rated power per sub per the TL Magnum sensors.
Also has awesome bandwidth.

Ah, you have a truck. Pickup trucks can have some funky acoustics sometimes. What's your port mach or m/s (air velocity)? The higher you tune, the more port area you want.

My goals are pretty modest I think, I would like to get into the 150-152 db range. I would like to do this while maintaining a decent bandwidth, I'm not looking for a super low end monster but would be nice to be audible while moving some air. Will there be a big difference between 12^2 and 14^2?
Tell me about it... I have had a hard time getting numbers out of this truck. I have had a few people hear my current sub stage and swear it is doing over a 150, it seems to load great at the headrest but looses tons of steam at the dash. it could be something as simple as raising the box position a few inches from what I understand.
As far as the m/s goes, to be honest I have no idea what it is or how to determine what it is.

I'd love to have that much port area and tune low. I sacrificed bandwidth for more port area while keeping low tuning.
It's not what most people want, but I wanted a ground-pounder for demos and I'd like to hairtrick when I get the other sub back in.
Right now it doesn't play everything well, but the songs it does play well certainly slam

I fail.
I'm not sure that you can have *too much* port area... in theory.
But in practice, the problem that arises is the length that it needs to be.
