Ported Enclosure Design Help

[angrytrucker78 10+ year member]

Ok, I have a SI MAG 15" on the way. I would "like" to get it in a ported enclosure, but I have a feeling sealed is my only real option.

A pre-lim measurement of my hatch is 40" Max Ex Width, 19" Max Ex Depth, and 11" Max Ex Height(that's only because the sub would have to fire upwards as it's to large in circumference to be mounted vertically)

So with those measurements I'm at 3.99 after basket displacement, so that only leave .5 cu ft for vent displacement. I'm shooting to get 3.5 net@ 30hz.

This is gonna be impossible right?

Any light shed would be appreciated.

Not impossible. But the resulted port noise would make a sealed box the better solution.

x2, the port area would be so small that it would work against what u r going for

That's what I figured. But on the bright side, I'll be powering it with a Sundown 1500d gained down to around 1000-1200, it should still get pretty loud in my little car huh?

It's 300zx 2 seater, small....

Ok, I came up with a design that does fit. But the vent is gonna be real close to the back of the hatch. Is there a certain amount of space that is required to be in between the port and anything else?

the width of the port plus like 1/2" would work fine.
