heres a box im doin its 7 cubes net 3 6 inch ports that are 17" long tuned to about 38.5HZ i believe ( higher then i wanted) but the sub was hitting the one port so i had to cut them down a little
still need to pull the top off and resin.glass the ports to the inside of the box then lots of sanding, brace it then pull only set up out and try er out! not sure which was i want to fire the ports should i fire them back? they will only be about 2 1/2 inchs away from back of the trunk or i can fire ports into cabin of car pics!
