sure, it should work well...... the calculations i'm seeing puts the 36x18x18 at a little less than 4.7cuft though, right around 4.4 after all displacements..... that won't hurt anything though as it's still well inside the range....

I should add that this is if you're using a slot port @ 12sqin of port per cuft.... if you're going with a 6" aero then its just right..........

Now these are all internal dimensions, right?

all measurement are in inches

all measurement are in inches

but they are all the internal dimensions of the box, correct? I know that you probably know that external dimensions don't matter other than fitting it into the vehicle, but I'm just asking to be sure.

Also, what size is your port opening? What are the dimensions?

[R3ap3R 1]

the external dimensions are 36 x 18 x 18

the port is 3.5" wide and should be 16.5" tall

Did you plug your external dimensions into the box calculator?

Unless it asks for the thickness of the wood, then you should plug in your internal dimensions. My box is 18.5x17.75x32.5 internally, and after all displacements, it's only 4.35cuft... I didn't actually plug it into a calculator, but I'm thinkin' 4.7cuft is would be the volume if your external dimensions were really your internal dimensions. Better check that.
