    When it comes to polyfill, how should it be layed when there is a vertical port thats only several inches from the inside bottom?
    Its an Aero/slipstream 4" port, which has 2 flared ends. its tuned roughly 32-34hz and is vertical. I wasnt sure exactly how to stuff the box or how it effects airflow though the port.

    i planned to stuff it heavy hoping maybe it would help out the low end a bit. Should i staple it to all sides, leave loose or what?
    the kind i got is the mat layer type, so i don't think any will be able to exit the port

    I would use duct tape instead of staples,just to test it out.Let us know if and how it helped.

    so i'll layer it on sides of box except for bottom where port faces.
