i dont really understand the whole porting thing so i really have no idea, i just got on jl's website and seen each one needed 2 3in ports so i got four but im thinking about just getting 1 6in port or maybe 2 i just cant firgure out how long i should make the ports, and that equation to figure it out messes with my head!//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

so u think i should just get 1 8.75 flare becasuse i want it flared but i should make it prob about 20.88 in long to make it for a tuning at 30hz. Could you give me an online store to get some becasue i would have to order it from the local dealer and it will take for ever.
