So i built a 6.25 cu ft box tuned to high 20's and the port resonates on the inside of the box. This caint be heard from in the car but outside it can be. How can i strengthen the port and box to eliminate this without adding more screws? Would fiberglassing the inside not including the port area work? Im also looking to decrease my box volume just a smudge. Maybe half of 1 t^3
