I recently installed an 8" in a custom box to go inside my center console (see pic), it sounds great EXCEPT it bumps against the center console's plastic grill and since the sub is a little bigger than the grill and not perfectly centered, it bumps against the inside of the center console a little; this causes a really annoying buzz.
I recessed the sub inside the box, but it still sticks out a bit. The sub has a rubber gasket that covers the mounting holes, I'm not sure if that's helping or adding to this problem.
I can't rebuild the box, what is the best way to fix this? I know that when I stick my hand on the grill and apply some pressure, the buzzing stops. Should I tighten the grill down onto the sub? Or should I use some rubber pegs or something inside to try and push the grill further away from the sub and create some space for it to move?
Thanks, everyone has been real helpful as I've progressed through this install, I'm almost there!
