Trunk Rattles from Subwoofers

 

Unregistered guest
I have a 2004 Jetta and i have 2 12" subwoofers in my trunk with a 1400 watt amp. My trunk rattles really bad. You can hear it rattle inside the car and outside. I was wondering if there is anything i can put in my trunk to help it not to rattle because of the base. If you know of anything please let me know.

look on ebay for stuff similar to dynamat.. like fatmat, brownbread, edead, or similar. this matting lines the trunk against the metal, under the trim you see inside the trunk to reduce vibration and noise.
expanding spray foam works for areas the matting can't reach
another option is to have the trunk interior (under the trim panels) rhino-lined

tighten down all bolts and connectors that may be vibrating as well.

its a bit of work and some cost involved but the payoff is worth the effort.

Something else to keep in mind is firing your speakers fowared. Most people fire them backwards to get the best boom for their buck. Since you drive a jetta I am guessing you spent some money on your stereo. Look into getting a custon sealed box that fits tightly to the back of your seat. Ask the shop to set the face of the box about 2 inches back from the outside edges, and then scribe the edges to fit tight. You will get alot better sound quality, and if you drop the seat down you will notice it getting alot louder. I used this setup in a 1990 bereta, and loved it. Very hard hitting and alot better sound quality. Just as with the dynamat, a custom built box isn't cheap, but well worth the money if rattles piss you off like they do me.

try pulling the screws out and put a lock washer on them so they will stop comming loose. With the screws good and tight it shouldn't rattle to bad.

im not sure if this would work with something heavy like a spoiler, but i used rubber washers to prevent my license plate from rattling, and they work great. might not look too pretty unless ur car is black tho....

I have a 93 mustang and my spoiler used to rattle. I fixed it by rolling up pieces of paper and shoving it under the spoiler. Now I roll with pride.

I have an '87 honda crx. My system is a 560watt amp with 2 10's. It rattle the hell out of the hatchback. What would be a good material to save the hatch from rattling off? :-)Its pretty bad.

I don't care what you do, if your subs hit hard enough, something will rattle. Through all of my expeiences, there is only one good way to keep your trunk from rattling, and its a cheap one too. Turn the volume down:-)

why do people turn the subs where the magnets are out of the box does it hit harder or what.

well for some people they do it because the subs look cool, for example the audiobahn flames. the only reason i can think why else they would do it is because if you do that, its like a giant port for the sub

it's either done for the look like lee said, or you do it for space requirements. like if you have to make your box long and narrow, it'll still have the right cu.ft., but not be deep enough.
