are you sure you want it tuned that high? i'd think a grand am would peak lower than that (and why would your wife want an SPL box?).

anyways, i did the best i could with those dimensions:

http://www.subwoofertools.com/forum/ported-box.asp?Ew=36.5&Eh=14.5&Dia=6&Xmax=13&Vd=.1&NumW=2&Vb=3.8&Fb=60&Qts=&Vas=&Fs=&CE=0

make the port any bigger than that and it doesn't work (and the site changes the box dimensions for you). hopefully 84.5 sq in of port is enough.

45ish hertz should be sufficient.

o ya didnt even notice that i was half asleep earlier... 60hz is hella high like you wont have much response at all below like 45hz... im not sure about those subs but id prolly go more around 45-50 if its just for burpin.. and possibly a little more volume

Usually SPL oriented boxes are tuned an octive lower then your peak note.

It peaks at 60 to 64 hz there was no diff. inbetween there (or very little) this is just a second car im going to compete with towards the end of the season i ran through in a clinic before the show and played around with it and hit a 147 with box facing back...now i know ill gain if i flip the box subs on pass side and port on drivers i seen another grand am do a 152.7 like that but i deff. need to tune higher and foward fire the subs...now that might change the peak freq.? im not sure....

If no one has offered/committed, PM me and we can discuss some ideas I have.

Yes, there is a good chance that your peak freq will change if you face the subs differently then before.
