Port Help!?!?

[Davo2378 0]

Ok i need some more help trying to figger out how big to make my port, it is for two sa-15's on the saz-1500d .v2 in a 97 Blazer.

The box will be 19H, 38W, and 26D, subs up and port back.

But i wanna put the port on the bottom centered and i was going to make the port.

6H, 20W, and 19L, but that didnt give me enuff port area and i want it somewhere between 32 to 38 or so Hz.

So if someone could please help me out it would be much appreciative thanks.

Are those outer dimensions on the box?

That box is way bigger than needed.

What cubic feet are you going for?

You only need between 3 to 3.5^ft per SA-15. With what you gave for port it will be roughly 120^2in. Tune to 35hz would be 17.375" length.
