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

Hmm so how am I thumping away a pair of 6x9 8ohm Tang Band in the rear deck on my Mazda off a JL 300/2? Such blanket statements.
http://www.parts-express.com/tang-band-w69...woofer--264-837 Looky, 8 ohms. Thump thump thump no problem, just wire to a 4 ohm load. Rear fill, no care about stereo behind your head. (running them IB in the rear deck, they're seriously great speakers for the money and sound amazing after about 3-4 hours of play time once they soften up a little)

Just about any of those speakers would be suited for use in a car, some more than others due to resonant freq and sealed or ported volume requirements. Speakers are speakers, as long as you can drive them and house them correctly you can play them.
