I have 60" wide and 26" tall and 27" deep. I have no idea how to build the port there are so many ideas out there and and im lost! One guy told me to fire the woofers up to the roof and with a horizontal port, lower front. But i have one sub in there right now and the sub is fired to the windshield and its loud. But everyone i see has ther woofers firing to the roof. What should i do i need all the help i can get ask ur friends for ideas too. thanks
