Does anyone know how to deaden that buzzing sound from the subs in the trunk? Inside the car sounds good but outside you can hear the trunk rattling a little. also will removing the cloth/plastic stuff covering the trunk interior make it sound better?

 

I am having the same problem, some people say to use dynomat, but others have told me that it doesn't help to much. Anyone know for sure?

 

The idea is pretty much to take anything that rattles and either remove it, or weigh it down with something like dynamat so it's moving less, preferably at a low enough frequency that you won't hear it.
