1.9cuft 3/4 mdf box and what to install

Go a mate with a 1.9cuft avaible
He want loud and clear

I looked at trying a rexxx12 ported but i end up at 1.2cuft, and it not quiet enough i think

Ive never herd the xxx15 in sealed and cant find much on it in a sealed app.

Car is a g8 pontaic (same as mine)
But he has kids and need the boot

Sub will face to rear or 45deg rear side to fit in size

He mostly lissions to dance and r&b

And susgestions would held

A few options ive look at for him
Also no amp as of yet so will be close to max for whatever he choses(max 17/1800wrms)
