Hi There,Looks really good, mine didn't even look close to that. Respect for your tidiness
I did all mine last year and the part that reduced the noise the most was under the arch trim. I used one layer of the rubber sound deadening and a thin layer of foam.
I'd also recommend if you haven't already, doing doors. Silentcoat and then some dense acoustic foam for directly behind the speakers, adds a good amount of bass after.
How did you remove the side panels in the boot to get to the wheel arches?
Many thanks,
Nick
