Hey guys, it seems there is a slight vibration/rattle coming from the ports at higher volume. I have no idea what it could be anymore. I figured it were the black and red wires running by the center port. Sonic boom audio (canada) asked me to take the amp off and look inside and tape the wires to the wood frame. It didn't fix my issue unfortunately. Anyone have any idea what it could be?
Besides inspecting for anything loose inside, also check the rigidity of the ports. The outer ones angle inward above the bend. Make sure these are not touching the braces and can't wiggle enough to touch the braces.
