Buzzing from sub?, I'm getting an annoying buzz with my new custom sealed box Options

[Noahwhite2014]

So I made a sealed box that takes up the inside of the spare tire well and has a false floor baffle flush with the rear seats in the down position. The volume on the interior is around 2.85 cubic feet and there is cushion foam lining the floor pan in the back. The whole box is bolted down to the spare tire tie down hole and that is also the ground point I'm using for the amp. Here's a picture of it.

Looks great and sounds great, but at certain frequencies I get a buzz from my plastics in the back. I believe it's also buzzing the bumper and license plate bezel (not the license plate itself since it has a rubber "anti vibration" frame.

Anyone have a good way to quiet that crap down? Lol

For all intents and purposes a sub amp is a sub amp, it's not like you're going to really hear any distortion. As long as it's set properly I doubt any of you could tell the difference between a Dual and a JL during a blind listening test. Where the higher end stuff shines is when it's being pushed hard, where you need better audio shaping, where you need more variability with configuration, where you need to run very low ohm loads, etc. For what he's doing that Dual amp is adequate and NOT causing rattles.

Wood glue and liquid nails are two different classes of adhesive. Wood glue is better for the box because it soaks into the MDF and creates a bond that's more than just the two edges pushed together, liquid nails is a surface adhesive which would be ideal for bonding the box to the sheet metal of the trunk floor. Use the right glue for the right job.
