Sub Boot Rattle

[-VY LoVeR-]

Hey guys

I got a VY S2 Equipe with the spoiler and towbar attachment and whenever i turn my sub up it just seems to rattle the hell out of the boot. Ive taken it to a few places but no one seems to be able to do anything they all just say turn it down
When i pull the centre back seat down it seems to calm down a bit but it still rattles.
Anyone know how to stop it?

do you know whats rattling??
if its the plate then either put some backing behind it or glue it to the car
alternatively you would need some sound deadening materials such as dynamat andthat is to be placed in the boot behind the side panels

Yeah i got told it could be the towbar or fuel tank cover. Even if i hold the spoiler down it seems to calm down. You cant hear it inside the car but its not a great look when you see a car rattling. Where a good place to get dynamat and what sort of price will i be looking at?
