2007 civic EX trunk rattling
 

I recently had my sound system installed, it's just a JL12w3, 300 watt sub.

The trunk rattles when certain lows hit, I was wondering if anyone had a good suggestion for this, or if maybe verify that a dynamat trunk install would solve this issue?

I plan on putting a lot more power in that trunk, and I wouldn't care about the rattling if I couldn't hear it on the inside of the car.

I already shoved cut up t-shirts and old socks under the rear speakers to stop that piece from rattling which worked, and messed around with my license plate to get that to stop.

All advice is highly appreciated, thanks

How did you get your license plate to stop rattling?
