Ordered some parts for my new box, building this weekend. Feedback appreciated.

Ordered a 4" diameter, 17" length precision port, as well as a terminal cup from parts express. I'm hoping it will be in by this weekend. I'm going to build a 1.9 cu ft box tuned to 29hz for my 12w7 (pic below shows a 1.8 cu ft, but I've given it a tad more internal volume). I'm hoping it'll turn out as good as I think. Still not 100% on the tuning, but for daily driving, I think it's good.

Box Plans:

Anyone have different suggestions? Limited to 15" high, and 31" wide. Like to stay under 14" deep.

I'm sure one 4" port will work but if it was me i probably would have used 2, but thats your choice.

A 4" aero on my brahma was enough. It does chuff some at high spl and low freq but from in the car you can't hear that through the trunk. If I had a hatch or truck though, I would use a bigger port.

Yea, I messed around with the design. There's no way I can use 2 ports in that small of a space. If I go with a 4" port I get 42" length for each of the two ports. But, like IamDeMan said, it'll be in the trunk so I likely won't hear any port noise.
