[01DangerRanger]

im gonna build a box that will hold my p3shallow 12 and my p2 8's in the back of my regular cab ranger and im gonna wall off the back and have everything in this one box. im gonna get some RF 6*9's to add to the box. how much air should be for the 6*9's

shouldn't mix sub sizes. or models.

6x9s, sealed, probably... ~.2-.4 cubes.

the box will have seperate sealed areas for each sub and 6*9 and 1 amp for the 12 and another for the 8's and another for the doors and rears
