If you look at the post in the thread, I didn't make it bold. Weird.

i made it bold because what you stated made no sense at all

O.k. Ported is for larger areas. You get that? Some people make the trunk into the box and port it to the rear dash, making the inside of the car a box itself. Open the windows and it's going to quake. Maybe i'm wording this wrong but that's what happens.

when people use the trunks as a box its called infinite baffle and you cannot port infinite baffle. what you are talking about is sealing the sub off into the cabin and using aero ports into the rear deck to act as if a blow through?

Oh really? I had some near field studio monitors that were ported, and guess what, they were designed for SMALL listening areas!

OTOH, if you meant ported enclosures are generally larger than sealed enclosures, you would be correct. There is a whole plethora of theory I can get into regarding the pros and cons of each type of enclosure, but I don't feel like getting into it right now.

I would NEVER recommend porting through the deck, unless one replaced their rear deck and have the speakers and the port all facing in the same direction. Even then, I wouldn't recommend this because the sun will make short work of most subwoofer surrounds. Another instance where I would recommend porting through the rear deck would be if one was to design a 6th order bandpass enclosure. Then again, I once did a 6th order bandpass in one of my vehicles and didn't care for it because it was a 2 note wonder.

For most trunk installations, I generally recommend the sub facing back with the port either out the side loading off the wheel well or facing back to keep port noise to a minimum.

For those who wish to seal their ported subwoofer enclosure off into the cabin via a direct fire method, I would recommend sub forward, port forward. Then again, I have also seen my share of verts where the rear seat was deleted and that is where the subwoofer enclosure was installed. I've also seen clever implementations of audio compressors in verts too, but that is a whole other topic.
