Imo: 1-12 or 2-10s in the correct box would sound better, i highly doubt there is enough room to have a box large enough to supply enough cubic feet for 4 even shallow subs... All my recent homework says theres barely enough for two shallow 10s (with pre fab boxes anyways) im thinking ill try a fosgate p3 shollow 12 in. 1.0ft box and hope for the best, if our program will spit out a cut sheet for a 1.4ish foot ported box @ like 32-33hz ill be building a box. With the room aval, i dont have real high expectations so im not trying to get crazy.
But yea like i said, highly doubt (especially kicker) 4 10s in half the required square footage would sound even almost good
