The ports on this thing are not natural. There appears to be only one port but there are three. One port from each subs chamber into the middle chamber where there is a port to the outside which you see here. Sounds pretty damn good if I could only get rid of my slight roof rattle, any one know how to fix that?
dynamat it or figure out where the rattles are and put things betwween the rattling pieces. cloth works well. Thas what i did to my roof and trunk helped alot.
