    how much polyfil is enough?

    I want to use polyfil in a 1.6 cubic foot box after sub displacement to make the sub act as if it was in a 2 cubic foot box. What are the guidelines behind polyfil usage? Is what I want to do even possible?

    All day I'm clippin'
    voltage be dippin'
    I don't give a damn,
    cause my trunk always hittin'!

    creating a proper sound wave. Step one, turn it up until clipping. Step two, done.

    Not gonna happen. it might cover for .1 to .2 cubic feet max but not .4. Your going to need a lot more and you'll be introducing a lot of heat if you over stuff it.
