I am building a ported box for two 12" kicker CVRs. It's going to be 38" wide by 16" high by 17" deep. This is going in the trunk of my 1999 Altima.

I have the bottom cut and the left side. I'm not sure about the port measurements. I wanted to ask here before I went any further.

Here's what I have so far:

Top/Bottom: 38" x 17"
Left side: 14.5" x 15.5"
Right(Port) side: 14.5" x 16.25"
Back: 38" x 14.5"

I want the tuning to be 34hz

Can anyone help me out with the dimensions of the front piece, port piece 1 and port piece 2?

Thanks!

The RE calculator is a good tool... but it's often misleading.

Are those your outside measurements or inside measurements?

Outside measurements. I just did the RE calculator and went through the tutorial on how to design a ported box. Measurements were off by a bit.

I know those dimensions will fit in my trunk. I definitely want the tuning to be 34hz. I have the sides, I just need to know what the dimensions of the port pieces are and the front side. I know the port will be 3-4 inches wide. I'm just a little confused on how to calculate the port pieces and the width of the port area.
