That port is way too small. And you aren’t understanding 12volt measuring, you inputed gross volume instead of net volume, a port has volume itself and would tune that gross volume you calculated to a smaller volume, called a net volume. You enter a net volume into that port calculator. And you are not understand recommendations in reference to sizing. You put the port size recommendation of one subwoofer on 3 subwoofers, you should of tripled it. But even if you listen to recommendations and calculate correctly doesn’t mean that’s the best enclosure. It’ll be a decent to good enclosure. But not the best. The only way to design the best enclosure on a setup is to calculate the subwoofers parameter in reference to the rms of whatever amp you are using. So with that said, recommendations are just a safe call and not always the best call. Because rms changes the enclosure and port sizing and the parameters determine the sizing too. So the ONLY way to make a custom enclosure best to fit your car audio set up is to calculate the subwoofers and amp, in laymen terms. I can help you so you can get that crap out your trunk and turn it into something loud and sexy. Because a super small port like that smothers output and isn’t loud. Just let me know if you are trying to get loud.

I'd appreciate the help. I obviously don't understand box specs and building quite like I thought I did. Lol. Any help with box and port design would be great. Ive got about 37x16x16 to play with for space.

Needing some advice. I have 3 skar audio evl8d2 in a ported box. Single chamber. Ran calculations through 12volt for tuning to 36hz. They said port needed to be 2x6x4.6. I have a funny feeling that that is no where big enough. Can someone with a little more experience look at the measurements and tell me what the proper port size should be? Box size is 31x15x16 with 3/4 birch.
