I know you probably still hate me and all, but i have a question abou
ported boxs that i think you could help me with. I have a saturn 01sl
which means a very small trunk. I have a tampest and am about to buil
a 4^3 ft box but cant decide where to put the port. I am afraid tha
the box itself is going to cause problems with the transfer function o
my car, and really dont want to wall the trunk off either. I wa
thinking about having th port fire through my rear deck since there i
no rear fill there. Any problems with that and the fact the port won
be on the same side as the sub?

Thanks,
Stev

why would the box cause problems with the transfer function..??

Alot of folks do boxes like this with good results...

Maybe, maybe not...
Generally the primary function of the port is to tune the box so the
woofer makes the sounds you want it to make. In other words, you
can make the woofer system play a little lower or a little higher (more punch)
by tuning the port to difffernt frequencies.... For this it wont matter which
side of the box the port is located.

Another thing a port can do it ADD SOUND at certain frequencies, in other
words, MAKE YOUR BASS LOUDER... It does this at certain frequencies
because the sound coming though the port is in phase and ADDS to the woofer
sound.... Typicly for this to work predictably, you would want the port on the
face of the box with the woofer(s)....

But unpredictably, the port may be better or worse if NOT on the same side
of the box, depending on many variables such as location in the car and how
the sounds from port and woofer and their many reflections meet up at the
listening area of the car....

The only real way to tell is to try it and see... I dont think there is anything
inherantly bad about what you want to try....

Go for it.

"Honorable Eddie Runner"?

Must be a Canadian or Brit calling you, Eddie, because that's how you properly address a
member of Parliament ;)
