Hello CA, hows it going. Well long story short, my friends are eating away at me ordering sub boxes from me left and right. Here is my most recent one i am working on for my buddies truck. It will hold either 2 older Kenwood 10s or some of the new Kicker 10s. Enjoy!

Question: How in the world is the port length calculated on a fiberglass enclosure?

I would imagine its pretty easy to be off on tuning frequency when you don't have any specific dimensions from which to calculate the enclosure volume.

Fill the enclosure with small beads of foam, or something like that.
Pour the beads into a container of known volume.
Voila, there's your volume.

Unless he is using it in a boat, I think he will be alright, lol!

guesstimate and then double check with the method quoted bellow VVV

Uhh....Add bass to a trunk and voila you have a leaky trunk.I have seen it many times,espeially in trunks.They leak, the box soaks up the water and its toast.
Partical board is just a way to cut cost.Not my thing but if its all you can get and no one complains who cares.

But yes Req was right its like a big sponge,not as compacted as MDF.

yes that is true, im also not trying to argue, but this is going in a TRUCK not a TRUNK

The last box I built was out of particle board, and it held up just fine for over 3 years in the trunk of my car. Granted it wasn't a power house 2 12" Infinity subs off 300w each so it wasn't gonna bust the trunk apart. I am wondering what will happen when the resin hits it though seeing it soaks up water. Either way the wood working for the box sure does look good though. Looking forward to the next stages of the build.

After the box is resined, it won't matter how much water particleboard ***** up. Essentially, the wood won't ever touch water, the resin, filler, and/or paint will.

Well someone is likely to come in here in the future and argue his 2 cents so lets see what happens... Maybe i will fill the enclosure with water to see if the makes the bass hit harder................

LOL at those subs, I had some for like my second or third system. I blew them to ***** cause I didnt know what I was doing, but was fun none-the-less. Ahh, brings back memories

Yes they are quite something arent they? haha i bought them plus a 500w amp for $35 LOL anyways one has a torn voice coil. They are just my "test" subs. I always design my enclosures and use these to see if it sounds decent. If it makes these subs sound decent then most other subs should blow you away :)

You have to be sure to do that before you lay resin down, because otherwise, youre already too late. Unless you are going to adjust the port length after you glass then it's pretty much a guessing game.

Wierd, as I have had over 20 trunked cars and not one has every had a leaky trunk. Hell right now, I have all my equipment in my tire well and been that way going on 3 years. Have had trunk cars do over 150 and never had a problem with my trunk. No my rear window, that is a different story. I have also had some beaters with nothing but other problems with the car, but never had a leaky trunk.

So isn't like it happens with everyone. I guess it's certain cars maybe? I don't know, but I wouldn't not put a particle board box in there because it may leak. Odds are very slim IMO and my expierence. Also particle board boxs don't sound that bad. I was against them as well till I heard one about a year ago. Was very loud to say the least and still is holding up to this day .

Oh and his trunk don't leak either, lol!

OP- Box looks good.
