Jeff4661 Posted January 9, 2015 Report Share Posted January 9, 2015 The box looks good in regards to port area and such.. my opinion is the box is to big overall. Those subs are rated at 1200rms and that rockford fosgate 2500 builds more than rated power.. Now I'm not very familiar with digital designs Subs so take my opinion with caution. I just looked at the specs and for a sub with only 14mm xmax it just seems like 5 cubes is a little big for the power level you are running.. But if I am misstaken and the subs will take 2.5cubes a sub ported then by all means you have a great box design..

BoomZoom808 Posted January 10, 2015 Report Share Posted January 10, 2015 The DD site recommends 1.75 to 2.75 for a single 12 5.00^ft (3) 10" or (2) 12" or (1) 15" or 18" 80.0 sq" vent x 18" long DD box recommends more more port area, looks like you are using aero ports? If you are overpowering might want to go smaller if you are using aero's and are going to be fixed on port area smaller box should be ok 3.25^ft (4) 8" or (2) 10" or (1) 15" 52.0 sq" vent x 20" long 3.50^ft (4) 8" or (2) 12" or (1) 15" 56.0 sq" vent x 20" long 2010 Mazda 3s 2.5L Pioneer DEH-X9600BHS Knu OFC 1/0 SS Platinum AGM / XS Power XP750 Alpine PDX F-4 / Morel Maximo 5 + Coax 5 IA 10.1 / SSA XCON 12 Link to comment Share on other sites More sharing options...
