But, IMO 02zetechse has priceless advice and knows his game.

Butt kisser lol , but on a serious note, Teknique, center up the port when you do it . Putting the port one side or another will make it louder on the opposite front seat. So if you want all listeners to have a equal amount of base make sure to center it up . You will have to figure in the port length and port diameter to get the proper port tuning .

Basically it comes down to this ... your rear deck is at a set height , as is your enclosure . the only option to adjust "tuning" is to adjust the ports diameter , more diameter higher tuning ,opposite with less . All while the ports length stays stationary

Any time an enclosure is vented into a cabin, you will have a audible gain in output . Seats up is a sealed box inside a sealed box ... muffles the majority of output . now when the seat is down , it acts as another vented chamber .

hope I didnt get to technical for everyone

Teknique Oops, I didn't make it clear that I want to keep the seats up so I don't cut down on useable space. If the sound quality is good and it makes an actual difference I going to go for it. Thanks for the input guys

sam fisher But u wouldnt have to have em down

02Zetechse I would not recommend this because you have fold down seats, a port through the rear deck will not have any better output than with the seats down .

Teknique Thanks for the response SF, nice to know it works.

ztechse, why would you not recommend this? Is the sound quality diminished?

02Zetechse working on a new design , hopefully 12 10s in a 4th order bandpass with a gross volume of 24 cubic feet with room for batteries and amps

sam fisher Holy shit , lol . Thats whatsup , what did you put in all that space
10-17-2012 09:44 PM
02Zetechse um do a ported sub box with a 6" pvc "aero port " going through the center of the rear deck , flush mounted Finish it off with fiber glassing the rear deck carpet to contour the ports flare .


i reccoment against this but its your car . you could also try sub facing up port facing forward with your seat down . it acts like a poor 6th order bandpass box .


or just eliminate your trunk like i did ... not that big of a sacrifice
