I checked their site and a DC lvl 2 12 requires .75 cubic feet sealed and 1.25 cubic feet ported. Now most sealed 12's I'm familiar with (of decent quality) like 1-1.2 cubes a piece sealed... I built a very nice strong MDF box for under the back seat of my Supercrew f150 after bracing and displacement of subs it gives 1.24 cubes per each chamber for 2 12's.. (I've used this box with 3 other setups) My question is, in that airspace what would they like? Sealed or ported. I'm planning on running 750 watts to each. Should I port them ? I know it asks for that but 1.25 sounds REALLY small for 12's.
