My box isnt carpeted, so maybe thats the problem, but whats the best way to make sure you get a good seal? I just noticed there is some vibration in the rim around one of the screws on my fi. ive tried looking for silicone but i cant find anything that stays pliable and doesnt act like glue

The latter is what I ended up using for my temp fix until I build my new box

Duct tape can be used as well if you're not concerned about looks

Are your screws even tight in the box?

I've heard of people using non-hardening rope caulk... But I agree with ^^^, are the screw tight?

I adjusted the clutch on my drill and went around re-tightening all the screws. problem solved.

Good.

It's always those stupid little things you thought were fine in the first place.

Glad you fixed it!
