Just picked up my 2016 NX 200t AWD with the 10 speaker system. Absolutely love the car...except for the rattle I hear when I have the music turned up. I put some dampening material underneath the license plate holder, but it seems to be coming from the 8 inch sub in the trunk which makes it rattle. Seems like they should have used some dynamat or something. Wondering if anybody else is having this issue and if Lexus has done anything to rectify this small yet annoying problem to an otherwise superb vehicle.Thanks
