Built first box but realized I made a mistake...

[v3x]

I made a ported box for an EVL-12. About a week into having it in my car, I've noticed what seems like a big mistake: I placed the two port cuts backwards, so now the backside of the port is at least an inch wider than the part that comes out of the front of the box.... I hear port noise. It sort of sounds like a plastic grocery bag being blown by air. I've attached a rough picture of how it looks.

How bad is that for my sub? Should I scrap it and build a new box asap?

Having your port width off after the bend will shorten your effective port length (possibly raising tuning) and change volume, but as far as port noise goes it's usually caused by insufficient port area in my experience.

Did you design your own enclosure or use the Skar recommendations?
