    I messed up this box. Any advice? Too much airspace.

    Ok so I started to build a box for my 2004 Chevy ext cab for a single 10". The sub is a custom built (splaudio) sub and I was told 1.3-1.5 cuft. Well I actually have 1.75! That's before any displacements. Sub is around .1 I was gonna port with PVC but now I am thinking of building a square port just to use up some space. Anyone have any ideas? Here's a couple pics of the unfinished box. I'm at a hold point. Lol.

    You could always throw a few 2 x 4's in there to take up some space and use them as bracing or you could partition off part of the enclosure

    Sub eats up .1 port will eat up probably .2 or more so 1.75-.3=1.45 seems pretty much spot on.

    How do u figure port displacement is .2? I didn't figure it would be that much. Did I figure wrong? The section of the box on the right has internal of .09. I figured it would be around .05.

    Well I used two different programs to figure that out and they told me two different lengths. Lol. I'm trying to stay between 32-35hz. One said 8 1/8" and the other said 10 7/8". That was with a square port. 2 3/4". @33hz. I was just gonna go with 2 3/4" , 9" long.

    Sub is going to downfire. I have 1.5" from floor to bottom of box. The magnet will have .75" on one side and 2" on other side and 1.25" across middle of air space to breath. I hope that's enough. Inside and out.

    Yes I can. I can put it close to the front on the small side firing out. But don't I have to stay a certain distance from the walls?

    Ok. Well I'm fixing to put the 4"@16" long. Does the end inside the box need to be braced?

    I personally wouldnt worry about bracing since your box is pretty small. Could brace with dowel rods if you really wanted to.
