I have 1 Nvx vcw 104 sub that is currently in a sealed prefab box. I am wanting to build a vented port box and have never done one before. I'm looking for more output. It's going in a Ford Expedition so room really isn't a issue except I don't want anything too big. So only as big as it has to be. Please help with dimensions of the box.
Thanks in advance

 

I'm going to tackle building a vented box for 1 Nvx vcw 104. Specs for the box are going to be 1.5 cu ft. Tuned at 33 Hz
My max dimensions are 17" w, 18" h, 30" d.
I need help designing this box as I'm new to vented box building, so any help and details will be greatly appreciated.
Thanks in advance for your help.

 

it is better to use a round port for this box . you have to calculate volume of the port too
