How to stop the trunk rattle in my 2002 honda civic lx 4dr from my subwoofers?

I keep having emberassing trunk rattle in my trunk from my subwoofers, and i would really like to kknow if anyone knows how to stop the rattle?

You could put sound dampening on the inside of the trunk. I have tried FatMat sound dampening and it has helped alot. You can buy the sound dampening on Amazon for about $26 with free shipping.

You can use Dynamat or other brand of sound dampening material.

Turn down the music so it doesn't shake the car to pieces. I'm sure all drivers around you would appreciate that.
