So I was looking at pics of banginAltima's Altima and noticed the external aero ports were facing into the car thru the folded down rear seats.

I'm building a box for 2 Fully Loaded 15" BL's and was wondering if I can do something similar. However, theres a catch to my set up.

I have a 88' Grand Marquis that has a solid, non-folding rear seat. So I was wondering if I could make custom external aero ports thru my rear deck

between the 2 6X9's. Would that have the same effect as it did in Altima's car? He gained about 4Db when he re-designed the box and port set-up.

Or am I just being unrealistic?

This is his set up

its done all the time..i cant say ur gonna see a 4 db increase bc its all install dependent...just make it look clean

I say ditch the 6x9s, and vent through there.

I would love to ditch the 6X9's if it was an SPL only car. But its my daily driver. Sure it'll do an easy 145 when I'm done but I want the Mid range and Highs to go along with it as well, not just a 5000 lbs bass box. And I can DEFINITELY make it look clean and posses the technology to tune it to exactly what I want....

The pressure from the subs will just distort the 6x9s if not blow them.

The 6X9's are baffled so they don't distort.
