Update for anyone interested.
Yall were correct with the tuning. Made one port to the recommended size, 3x5, and it had no low end at all. Didn't really test it but prolly anything below mid 40hz was very quiet and into the 30's was just not there.
So I remade the port with a 2x11.5 pipe which tuned it to about 30hz and it sounds much better. Way more low end punch then it had before sealed. Also have a plate made so I can swap it back to sealed if I ever feel the need for some change lol

Made one port to the recommended size, 3x5,

Was this 3x5 port recommendation for 1 or2 subs?

The 3x5 is just for one. My box has two separate chambers, I made a port for each side.
