Hey, I don't know if this is a stupid question, but I am trying to figure this stuff out. I'm kind of new to all this. Would putting a 15" SSD in a 2.5ft^3 box, thats after displacement and all, be bad for the sub?? The websites specs are 3-4 cubes, but I am trying to help a friend of mine figure out how to build his box for his small trunk. I know it's not good to have too little airspace for a sub, but I was wondering if that difference would be ok?
