Sundown SA12 port area?

[Brian21699]

Will a 3 inch aeroport be enough in just under 1.5 cubes? Or do I have to use a 4? I would have to cut out some of the plastics of my truck to put a 4, but a 3 will fit perfect. @sundownz

Sub is already there in a box. If I can fit it, I'm gonna add onto the box. But that's gonna be a couple of weeks. I'm ready to port it now and go get metered again. 130.7 legal ain't cutting it for me.

port takes up space, sub takes up space. You are not gonna get adequate port area nor low enough tuning to make it worthwhile. You Might gain a tiny bit but you will sound peaky. To be honest your current box is only good enough for a 10. As in a 10 will get louder and sound better in that box than a 12.

I already accounted for the sub and the port will be external. I'm probably gonna end up swapping to a 10, but for now I have a 12.
