How do I stuff my sealed sub box for the best possible sound of the subwoofer? I have read that for every cu ft the box is to use one pound of fill. Is this correct? Also do you tightly pack the sub box balling up a one solid piece or do you cut it up and place it directly to each inner side of the box? If balled up, how far should it be away from the back of the speaker cone?

 

The only reason to use fill is if you only have limited room for a small box, but need a big box. If the box is properly sized for your sub, no fill should be used.

 

I didn't use fill in mine i just painted the inner with stone guard/deadener
