I can't help you with this one. But https://diyaudiocorner.tripod.com/formula.htm has a section on this type of alignment and might help you out. Note that it warns: "Bandpass enclosures are best designed with a good software program, as tuning and enclosure changes can produce endless alignment variations viewable on your pc."

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

So you can roughly support 2000 Watts for a short time, but yet you have 2 2500 watt speakers.
Have you considered using one woofer, these subs need a huge box to sound right, I have played with them and in the end didnt like the way I they turned out for street.
You need a ton of power, and a ton of room to build a box for them. my reccomendations are 3-4cu ft for a 10 5-6cu ft for a single 12 and 8-10 for a single 18.
just my suggestions from what I have tested and built for stret setups using these woofers.

That is for a daily driver. I tried alot of smaller boxes, and they never sound right. they are either really sloppy, or hardly put out anything. These subs displace nearly .5cu ft by themselves, they are huge, and require a ton of power and a ton of space to run correctly for street use.
