I just finished my wall in my car heres the details

2001 cavalier

2 dc xl 15's

8.4 cubes after dis.

going to be tuned right around 36 hertz

thats were i need help

before i cut the holes for subs and port i need some opinions on which setup to do

one sub behind each headrest and port in the middle of subs, above the subs, or below the subs..

also maybe putting one behind passenger headrest one in the middle and the port at drivers headrest which is personally the one ive heard is the best for TL numbers

any opinions are helpful thanks in advance
