Default burp box port area

I'm building a "burp box" for my truck but not sure how much port area is too much? Box will be 6 cubes with either a single 10" or 12" aero. 12" is 18.84" per cube and the 10" is 13" per cube. I'm only tuning to 40hz since the truck peaks at 42. Question is, will the 12" port be louder and would it be safe to play music with that kind of port area? When I say music, I mean the typical songs used in db drag that are 40-47hz

What sub? A DD or an SQ/AQ would love a lot of port. Other Subs, not so much

Keep in mind also that the efficiency of aero's allows for lower sq area requirement. So even 13^2 on an aero is quite a bit

I've been running aeros for a while now so I know about the port area for daily. I'm running just under 10" per cube now but that's for regular box. I'm looking for port area with a burp box. I think 13" is just at the upper end for daily use and I know more port area is usually best for burp boxes. Just don't know if 18" is too much

there's really no such thing as too much port area within reason

I'd do the 12"
