Ok so I've had my IDQ12v2 sitting in the room for a while now collecting dust. I definitely need to get this hooked up in my car and take my crappy Rockford Punch P3 out. I was wondering what would be the best size to make the box for it. After searching I get either .8 to 1 cubic foot so I'm not sure what would be the best to go with. For now it will be running off of an Infinity Kappa five getting 200 watts at four ohms (dual 2ohm voicecoil). I know the IDQs aren't known for getting loud but I would like decent output from it.
