Does anyone have any experience building sub boxes? I want to build a small box for my truck and I don't even know where to start. Plywood and carpet?

 

Particle board or plywood - from what I hear, particle board has a higher density, so it's the most commonly used. Carpet is also a good thing, but lots of wood/carpenter's glue, plenty of tacky glue to afix the carpet to the box, and a good idea of the mathematical calculations to figure out what your dimensions will fit.

Don't think you can fit a 15" sub behind the seat of your compact mini truck that doesn't have a king-cab. Build the box on paper, calculate the volume of airspace, then buy the subwoofer to match.

 

I've got a 4 runner, so I have the passenger's foot space to play with, I want to try to fit a 10" in a 14W x 13L x 8H box

 

Ideally you'll be using MDF (Medium Density Fiberboard). MUCH stronger than particle board. You'll also want to use some caulk to seal it all up real tight. You also need to get the cubic air volume that is ideal for the particular sub you're going to be using and for what type of box (ported, sealed, bandpass). I'm sure if you google it there would be plenty of instructional how-to's.

+1 ... pretty much summed it up for you right there. As long as your not doing any crazy angles or anything like that, it should be a pretty straight forward build. MDF board from Lowes or Home Depot and some good seal on the inside of the box and your good to go

 

well the only problem is there is kind of an angle that I have to acount for.

The box has to be shaped like this:
______
|..........|
|..........|
|.../ \...|

Plus I need a table saw, I've got a sawzall and a jig saw, I think the jig saw could do it, but not the greatest straight lines.

I wonder if I should just take it to a shop. I love a good challenge though but it'd probably come out crooked.

 

I've got a portable rotary saw you can borrow if you need one.

LMK.

 

I think I have a rotary saw attachment for my dremel, I'm more concerned with the straight lines to be honest. Maybe I can go to the wood department of my college.

 

You want to use 3/4" mdf. Straight lines are key as you want it to be air tight. If you seal it with silicon, make sure that you let it dry for a couple of days as the gases released from the silicon will destroy the speaker cone.

 

what year is your 4runner?

mine's a 90. i just built a simple rectangular SEALED box and it's very good.

of course going with really good ub (well from back then) helps...
