I've heard about this, apparently it increases output or helps with cancellation...which I definitely need But how do you do this? Do you extend the port out of the box to the rear deck? I'm curious on how this works...

I guess you would take out your rear speakers or cut holes and extend areorports up through the rear deck. THat is what I think you would do.

You have to invert your port. So basicly take your port from the inside and make it stick out the box. If you were to take your subs out and look in it would look like you would normaly see on the outside. Tuning stays the same.

so which way does the sub fire and do you need to completely seal the trunk from the interior?

That is the million dollar question. I would guess you would fire the subs forward if you have a folding seat and seal it off from the trunk.

ok so we face the sub forward, yes we have fold down seats. why not put the port on the same plane as the subs behind the fold down seat and then seal the trunk off from the interior? or is it not really necc. to seal the trunk anymore than the factory did? i have an actual trunk no hatchback if it helps.

For SQ I would imagine firing subs forward on same plane of ports,but if you must port it through the deck I would fire the subs to the rear to get more sub-bass but you may encounter some cancelation by porting thru the deck.Also if you wanted, You could design a bandpass enclosure and port through the deck with with zero cancelation but the trade off might be a one note wonder. So it's a toss up. I hope this helped ya!

Tuning would not stay the same. It would be slighlty different. You are gaining some box volume by not having the port take up any space. So therefore, with the same size port, the tuning would be lower. The difference would be minimal though, and you probably wouldn't be able to tell anyway.

ummm, the term porting your rear deck refers to nothing more than having vents in the deck to let the bass go through (when your seats dont fold down)
dont actually have a 'port' tube in the rear deck!
just a hole so the sound can excape,instead of being trapped in the trunk
