Rear Dash rattling...
 

So i got my system all hooked up. And when it hits on the lows, all i hear is vibration from the rear deck. So...I looked into it. I found that a lot of the vibration is coming from the rear brake light cover. There's a gap between the tail light cover and the rear deck, so i put some double sided foam in between it. The good stuff, not the 3M kind. the white stuff. It seems to be much better. I just need to put some more. Any kind of insulation there will do...just a thought
