Serious help needed crossfire c5 15s

[Nextlevelvapors]

Thanks so much for the input thus far. It is a 06 grand cherokee. Subs are c5 d4 15s. I wired them to 1 ohm on a crossfire c5 1000d amp. So they are getting decent power. Ive had 12s bang twice as hard with a 500 watt amp lol. I have always had a good friend who does spl comps build my boxes but he passed away last year so im almost lost. Anymore insight would be great on where to start here. Like I said id be more than happy to pay for a cut sheet building the box is not a pproblem. Im just bad with math lol

Max measurement I just got is 43 inches wide id like to go no higher than 22 inches which is what this box is at and I can go as far into the cab as possible to get the best sound

So here is a suggestion, power: to subs rated, amp subsonic filter to 28Hz, port clearance 4", figure is just an assembly guide:

NOTE: You don't need all the bracing shown in the figure, just one top to bottom brace and the port brace will suffice.
