Trunk Rattle Problems

Hello. I have two 12" Audiopipe subs in my 1988 Oldsmobile Cutlass Supreme.  The problem I'm having is that my trunk lid rattles a lot.  Is there any ideas to stop this or even reduce it?

I forgot to mention, the the subs are in a sealed box. Does it matter the size of the box?  The box is pretty big and I would like to reduce the size so that I can put it up closer to my back seat in the trunk.

Try dynamat or what our shop sells, stinger roadkill...  Coat the entire inside of the trunk lid using a heat gun to shape the matting so it will stick to curves and crevices...  You can also fill in any holes with a spray dampening material...  Also, cut a piece and put it on the backside of your liscence plate.  This may not completely solve the problem, but it is a definate start...Jesse

I like to use Brown Bread http://www.b-quiet.com/brownbread.html have used both brown bread and dynamat and find that brown bread is just as good as dynamat and easier to install at a fraction of the cost. Also do as JellyNutz says with the hard to reach places and get some canned foam to fill any unnecessary holes or crevices. But any ways is sure to dynamat the whole trunk. With the trunk lid you can apply 2 layers as it almost doubles its effectiveness As far as the size of the enclosure usually sealed enclosures are not that large.  Each individual sub has parameters which are used to calculate the correct volume of the enclosure. You can not take any box and plug any sub into it like a lot of people do.  If you give me the make and model # of your sub I will try to give you the correct volume for your enclosure.

I have 2 Audiopipe TS-R12s.

Here are the specs provided by the manufacture http://www.audiopipe.com/Specs.asp?Productid=TS-R12&NumOfSpecs=2I would run them in a sealed box with a volume of 1.0 cu/ft. You can use the 12volts volume calculator https://www.the12volt.com/caraudio/boxcalcs.asp#rec to build a 1.0 cu/ft box. Hope this helps if you have any more questions don’t hesitate to ask

thanks for the info.

Kinda depends upon the application location.  If it were me, I would get a little of both.

Use the stickeiest stuff on vertical locations and the less sticky on horizontal locations.  I would suggest buying about two to three cans of spray foam to pump into all the cracks and creveses between the body panels and frame work and to fill in big holes in areas.  It may sound a little messy but the end results will be spectacular.  (just make sure you pay attention to where you cars venting runs so you don't fill them.)
