Whole car is rattling

[brand22b]

Ok so I have had 4 12s in my alero for a while now and it seems like I hear something new that is rattling all of the time... The trunk is the worst. (That plastic piece that holds the license plate on). Does anyone know how I could get that to stop rattling without using dynamax. Also the top of the trunk rattles pretty bad too.

why dont you want to use dynomat?

well you can try screwing the plastic frame tighter.

for the trunk lid see where the noise is coming from so you can stop it.

as for the trunk seen people use spray foam, or foam tubes to keep some of the rattles quite.

hope it helps!

in the process of putting a sub in as well. been looking around to see where my week points are, but im using a sound deading material.
