4 RL-p 12" in 1.25cubes each ported, Is it enough?

imo 3 much more ideal, send them in for recones...

Ok I did some mesuring, and if I cut my rear seat (make it 2 buckets from a 60/40 bench), I can get enough to give them 1.55 each. What's your thoughts on that?

1.55 net, after port? How much port area and tuned to what?

I'd still say play it safe with 3 you won't have to worry about squeezing the margins. Plus you can double up all the walls so you get less flex, making it more efficient.

Net after all displacement tuned to 33Hz with 79sq" of port. Going off the site optimal is 1.5 at 34Hz.

I'd still say the 3 but it's ultimately up to you. I'd also recommend more port area, my single 10" sub has about 38 square inches.
