What ft^3 for sealed v3 D2 mag 15"

I'm putting the sub into a sealed enclose in the trunk in the back
with fiberglass over it so you only see the sub in the trunk. what ft^3 do you
recommend for this? it says 2.3 to 3 ft^3 for sealed on the 15". i have a cadence amp putting out 1200 at 1ohm. This is going into a 2001 CLK55

any input would be great, I don't know what 2.3 compared to 3 will do for me
and i can't afford to make a few boxes.

this was in a Ported box in my old car and it hit so hard people would get out of my car

Anything between 2.5 and 3 ft^3 will be just fine. Anything larger is not necessary and anything smaller will hinder performance.

What is the difference between 2.5 and 3 in sound? That is what I don't understand.

You'll get a tad more low end extension in 3 ft^3 than you will with 2.5 ft^3.
