...cubic feet does a 12" cvx need at 1ohm? Does anyone have any info, pictures, or knows where i can find pictures on how to remove the backseat, the headliner, door panel, and on the thing between the seat and the back window on a c5 a6? I'm going to dynamat the car, I've already started on the trunk door, but have more spots to go. I need this info, so I can get started. Also does anyone know how much cubic feet does a 12" kicker cvx need when its wired down to 1ohm? I have 3 of them, and I want to build a custom box for them.
