Marlo Stanfield Posted November 30, 2009 Report Share Posted November 30, 2009 You're gonna need to post what your dimensions are first... Then I highly doubt that someone is gonna design you a 4th order for free. 1998 Ford Explorer Eddie Bauer... New setup, old ride... QX56 is staying stock til I get loud... It's only getting walled off if I don't meet my goal @ SBN. Pioneer AVIC-N2 (12) 12" RE SXs old model.... (3) AB VFL 500.1 @ 1ohm each Dual 300amp Ohio Gen alts.... (10) Northstar NSB-125s 26ft3 @ 33hz w/ a ton of port area 156.5 @ 40hz @ dash, Db Drag style / 153.2 Bassrace Link to comment Share on other sites More sharing options...
