Dynamat Dynaliner - Thickness install question

[phraza]

Hey all,

Tried searching for a while and can't find an exact answer. Just been a bit of advice from someone that has done the below before.

Basically I've stripped the cab, painted the floor with rust paint and added 1 layer of Dynamat Xtreme (see photo below).

I've already bought an ACC carpet set with the jute backing already on it.

I want to add a layer of Dynamat Dynaliner on top of the current Dynamat Xtreme but am unsure of what thickness to do it (Dynaliner comes in 1/8, 1/4 and 1/2 thicknesses).

Has anyone used Dynaliner under a carpet set with the jute backing? I don't want to put too thick Dynaliner down that it affects the carpet and how it sits.

I've taken out the original cardboard firewall padding too (was pretty worn down).

Any advice is muchly appreciated!
