Decaf Posted April 3, 2008 Report Posted April 3, 2008 i hope u mean 26cubes total if so ~300sqin port ~34hz daily, ~40hz burb (cause im guessing u have a 4 door (~43hz 2 door) and they peak a little lower usually) thats a start but as a rule of thumb, always tune lower first, so you can just cut off extra off the end of the port to raise tuning if u need to, my .02c are you using the xxx @ 4ohms? thatll be nice
