If you want to go crazy my single 12 Alpine type x is pounding harder than many multiple subs. Go two type r's if your wanting the symmetry of dual subs, but my single twelve in a slot ported box only takes roughly two cubic feet for a box, and one for sealed. And it is plenty loud, so far hitting 145.1 DB's.
I bought a red car, because everyone knows red is the fastest.
