Fixing rear deck rattles

[DISCOUNTLASIX]

I'm not sure if this should go in vehicle issues,ICE,or DIY so I'm putting it here.
Just wanted to let you guys know that I made a video showing how I compeltely stopped my rear deck from rattling using some socks :3
Can't see it unless you look so it's good for aesthetics.
This is to fix rattles caused by subwoofers.
