    Is there an accurate way to find the internal volume of a fiberglass enclosure? I've researched the net and came up dry. I know that rough measurements can be taken and solved, but I don't think this is very accurate. Thanks in advance.

    So fill the enclosure with the peanuts, then pour them into something of known volume? Does this sound about right? Thanks guys

    Well you can use any box of similar size.

    Fill the glass box up and then move peanuts to "measuring" box...Volume is LxHxW.

    Just measure the height of the peanutes and multiply the length and width of the box...divide by 1728 and your set for the internal volume.

    lol yeah i've hear of using water but it prolly was a major pain in the rectum.

    I mean you'd really know if you had any air/water leaks lol.

    Water will work as long as any and all mdf is sealed with resin. Otherwise stick to packing peanuts . I use a known volume cardboard box to pre measure the peanuts as I dump them into the enclosure. :)
