hey guys im looking to build my first fiberglass enclosure and was wondering if you guys could help me guesstimate how much air space is in this enclosure. I will be building one basically identical.


Any help is greatly appreciated!!!

hell if i know. no way to know really. so i will say 1.24359 cf.

thats exactly why i asked for a guesstimate. I know nobody will be able to know exactly. im just looking for a range as I have no perception of how much it is. Im looking like an answer of "between .75-1.0" or somethin of the likes. I know alot of people have building experience and might be able to help me out on this one :)

Get a bunch of packing peanuts and fill it loosely. Then remove the peanuts, place them in a box. Measure the dimenions of that box L x W and multiply by the height that the peanuts takes up.

grab a plastic bag and fill it up with peanut packing, then shove the bag in the area you're going to be building the enclosure, take out or add more peanuts as necessary to fill up the cavity. then place the peanuts in a cardboard box and measure how much volume you have available for the enclosure.

Logic says that you start with the non-variables and make the variables work from there. If that is the box you gotta have, then there is your first non-variable. Make the rest of your choices work with it. So I'd build the enclosure, measure it with the packing peanut method, then choose a sub, then decide on porting or staying sealed.

My truck has a small, shallow space to work with. That narrowed my sub choices down to 3 or 4 out of the hundreds of 10s on the market. By following the logic above I got great sound in a situation that many told me was impossible. I just had to think about what I was doing instead of grabbing the first sub that caught my eye and throwing it into a big, square box.
