No need to change polarity, but you can if you want to.

Only if u have more then one sub you need to look at the polarity.

Yes you need to switch polarity even if it's one sub.

[I feel air from the port]

nice testing and info neo frog...that's alot of good info...

[I feel air from the port]

If the cross sectional area of the window exceeds the total effective cone area of the enclosure and the volume of air inside the enclosure is about the same as the cab...then yes a window will choke it.

like opening a hatch or rear door for ex?

i would also like to add that the car changes tuning quite a bit some times. i thought i was tuned to 42hz (by any calculator it is) but its closer to 35hz once in the car

yeah i said port tuning...but anyway yes cabin changes everything indeed

[I feel air from the port]

Doesn't that only happen in extreme cars and the few others that are loaded off the air in the car?

yeah that's why i mention sometimes

[I feel air from the port]

i hate to sound stupid but what exactly is unloading? is that like bottoming out?

loading is when there is pressure...btw port tuning is not the end factor of how subwoofers load, don't forget f3 of the box..i have a box at about 7.1 cu ft. with a dd 9518 in it tuned at 42hz and i play a song like i luv your girl for ex. at 31hz fine...lots of deciding factors if the sub will bottom out..hell sometimes subs can bottom out just by opening a window.

[midbass "flex" and a sexy hairtrick]
