The sub and box seems to fart to much. Why is it doing this?

My mistake.

It isn't the box farting, vibrating. It is either the deck lid, something in the trunk.

Anything that I can do about that. Stuff the deck lid with insulation. Anybody find a solution on this?

well, only thing to control farting is a low-fiber diet and a bottle of beano. however, for your problem, i'm gonna throw a couple scenarios at you and give you solutions for them:

1: Your trunk lid is closed and your listening to your subs hit and you hear air pushing out or small vibrations by your rear quarter panels near where the rear sidemarker light is located.
answer: your trunk vents may be fluttering, sealing these holes up may stop your vibrations, or pulling the rubber gasket off may help.

2: Your trunk is open and you hear a heavy 'air escaping' type noise from your sub woofer
answer: place weather stripping on the underside of your sub mounting ring and drill it back in place

3: Your trunk lid is closed and you hear vibration, you know it's not your liscence plate, but if you look closely at the trunk lid at an angle, you notice it trying to lift off the back of your car.
answer: dynamat extreme on your entire trunk lid and a recommended spot patching or entire coating of dynamat original on flat surfaces, dynamat extreme on vertical surfaces.

4: Your trunk lid is closed and you hear a dull rumble coming from your bumper, as if something sounds lose or terribly wrong.
answer: look under rear bumper as subs are hitting...seriously crawl under and look for pieces of styrophoam inserts in your rear bumper shell, if you see them moving, or if you can physically move them around with your hand, wedge some pieces of dynamat underneath them to hold them up snuggly to prevent vibration and kill any free play that might be in the bumper shell.

5: there is still major vibration and you can't tell if it's from your back dash or your trunk lid.
answer: another solution is dynamatting your rear dash with dynamat original and replacing your back dash with just a plain layer of fabric on the sheet metal, or figuring some way to better secure the stock dash panel down

6: you hear a noise definately coming from your rear deck, and you see the third brake light moving.
answer: place weather stripping on the bottom edge underneath the third brake light casing and tighten any loose bolts there may be.

7: you hear noise coming from the trunklid and suspect your spoiler from being the culprit.
answer: though not a cosmetic solution, definately a solution at that, remove the spoiler and place dynamat underneath the pedistals that mount to your trunk lid and bolt your spoiler back on.

and finally..
8: you've sound deadened any and every surface on the back end of your car and you still have a tiny rattle.
answer: though not many have this problem, but is commonly done as a 'just in-case' measure, look at the two tensioner bars for your trunk lid and wrap each piece individually with dynamat. only around where they meet in the center and could possibly touch each other, is this necessary.

these are the solutions to problems i've had with my car, and there is virtually no rattle besides the rear dash panel, which will never stop rattling no matter what i do. blue there knows the meaning of sound deadening, but for some reason can't seem to kill the part of his sound system that keeps causing the rattling... infact, it only gets LOUDER!!! haha, j/k bud. anywho, hope this helps you out a bit and good luck.
peace
ps. brands of deadener that i know of: Tsunami Mat, Dynamat, eDead, Brownbead/b-quiet, RAAMat (sp i think), etc..

Where do I get this stuff?

demoninvictus

Best Buy, Circuit City, Tweeter, any car stereo specialty shop (ie custom shop), or you can search on the web for the brands that i mentioned. keep in mind, some products DO require a heatgun for the material to adhease properly, eitherwise it will just fall off or not stick at all.
