Extending the port of a ported subwoofer enclosure? Answered

Picture of

I'm planning to pimp out my car, i was wondering...
If i design my own subwoofer enclosure, i want to extend the port, so that the enclosure is vented right inside the car (not the trunk)

if i did that, would i have to re-calculate port diameter?

thanks!

Yes.  If it's longer the peak will be lower (iirc).

so i calculate the port as if the whole port was outside the enclosure?

I don't think so...  Use the total length and diameter to calculate the size.
