i just got subs put into my car- how do i stop the rattle in the trunk area?

Question

i bolted my lic plate tight to the car, but the trunk still vibrates from all the bass. No i do not want to get dynmat.

Answer 1

well subs are hard to stop vibration especially in the trunk IF u are not going to get Dynmat or any rubber insulation to keep out the sound the only options u have are turning the subs in a different direction/ or moving them so that the vibrations dont hit certain areas of the trunk so bad.....Or to tweak your amp so there is less vibrations in the speakers when the bass is thumping...Also check to make sure the box/enclosure is sealed tightly to prevent any sound leakage .much luck

Answer 2

If your worried about the cost of Dynamat, Tar paper is almost the same thing. But after building several cars I can say Dynamat is the best. What your looking for is something that's going to make the trunk lid for example, heavyer. Something that's not going to allow sound to transform into vibration. Dyanamat can be cut into smaller pieces and used in between the folds of the trunk lid.

Answer 3

The vibration is caused by the friction of 2 pieces of metal.

You need to isolate where the vibration is coming from and then either A) screw down the area tighter or B) foam it up so it doesnt rattle

Another option is to use expanda foam

but if u still have rattles then just dont turn it up, or turn ur bass down on ur head unit

Answer 4

Tighten up your trunk a bit, or slip some small pieces of rubber sheet between the gaps (of whatever you suspect is rattling). Is the inside of your trunk insulated with sound proofing materials? If not, get some professionals to get it done. If you want good return, you'll have to dump in some investments :P

Answer 5

it will be hard to stop ALL of the rattle without something like dynamat, if its still the plate you can just get a dynamat lic plate kit which is only around $10 and gives you a small piece of dyna to put behind the plate

Answer 6

You're going to need to find the source. Crank it up and put pressure on anything that might rattle (jack, bumper, tail light...) unitl you find the source. Then tighten everything down and use rubber gaskets/insulation to dampen the rattle. Good luck, this is a headache job, but worth it when it's done.

Answer 7

Dynomat or equivelant really is your only option. The rattles are coming from sheets of metal flexing, hitting one another, etc... and Dynomat or equivelant prevents this (if applied properly).

Good Luck!

Answer 8

Answer 9
