Hey guys/gals.

Im sure some of you have ran into this problem, and may have a fix. How can I stop my hatch from rattling from 2 much base?

Apply sound deadening material to the hatch.
Elemental Design has some fairly inexpensive products designed for this (see the link).

 

ok yeah i have the same problem, but then on the right side of my XB i get this metalic thunk everytime the bass hits. I have two twelves sitting in the back and its starting to annoy me because sometimes i hear the metalic frame of the car rattle as the bass hits for a long period of time

 

I doubt the actual frame of the car is rattling, since it is pretty sturdy, but smaller metal attachment pieces might be. Basically, certain frequencies cause panels to resonate (especially metal) and air pressure from the subs causes vibration. Sound deadening material reduces the amount of vibration because it makes the area you put it on heavier, so it takes more force to move it.

I would trace the rattles to specific areas and apply the eDead stuff there. You might want to get a bass CD that has low frequency test tones to spot the rattles. It is also a good idea to deaden the area right around your subs. Also, make sure the noises are not coming from two metal pieces hitting each other or something. If that is the case, sometimes you can just put some sealant or foam between them.

 

My main rattle(s) come from my headliner right behind the front and rear dome lights and the passenger side seatbelt pillar thing(I have not been able to exactly pin-point this one yet),any info on how to remedy this and how hard is it?

And of course do not forget the rear license plate,rattled like crazy on my car and I just put some paper towel from work behind it,no more rattle from the rear...well,not as much..

 

I used weather stripping (for doors) around my under my license plate and in front of my license plate but behind my plate holder....that stopped the License plate from rattling.....but it seems like my entire hatch rattles......it doesnt do it except with big base music.......

Sound deadening prolly wont work...im thinking I have to some how put extra foam on the hatch to keep it from rattling.....when i push down on the hatch really hard it deadens the rattle.

Any ideas?

 

All you can really do with the hatch lid is add mass to make it vibrate less, 'cuz it's a lot of glass. That is basically what you are doing by pushing down on it. You are applying resistance to the force of the subs. It's either that or build some custom latches that make it more secure. You could also try changing the direction of the subs or ports so they do not push as much air towards a certain part.

The sound deadening thing works, because that is what professional installers and competitors in car audio use. Some of those people put dozens of subs in a car, and that makes a lot of noise. You basically have to strip down your car and deaden everything to stop vibration, and even then, you will prolly always have some noise if you have multiple subs pounding in the car at high volume.

The license plate rattle is common. Dynamat makes a plate frame kit that is made for that if you want a quick fix.

I saw a post on here about a rattle near the dome light that turned out to be the light wiring harness moving around.

You can add extra bolts/screws (might need to do some drilling) or tighten existing ones in areas to make panels more secure. Anytime you remove pieces (especially plastic interior stuff) it will be a little more loose and may vibrate more. The spare tire, jack, and fabric hatch cover also all have the potential to make noise.

 

the left side of my license plate light cover is loose and looks like the hole is cracked how can i get to the inside of the hatch to check it out
