Sound deadening mats

Did you completely cover those areas with the mats or only put random tiles on those areas? Asking because I want to buy only the amount of material I need for the doors and the back wall.

 

I'm partial to https://www.secondskinaudio.com/ myself. I've used several different brands before and it seems the easiest to work with, especially their CLD product. I really like the luxury liner pro which is a CCF & MLV combined.

 

Used Kilmat 80mil fr/theScamazon; applied to inside of outer door metal wherever I could get hand/part forearm to reach.
18Sft [17 shts of 10x16"] was under $40 and inner doors took about 6 sheets...no problem w/install...cleaned surfaces w/water sponge, followed by dilute Dawn, clean water sponge. Let dry, then papertoweled w/ Isopropyl alcohol.
Dont need rollers they all want to sell; since inner access is limited, cant see leverage from 6" long handle being much better than a 3/4 or 1" ID PVC pipe cut to length of middlefinger. Just press w/minor roll where you can...not a fine science.
Didnt go cray w/it and after closing cab and blasting speaks w/various tunes, you might find add'l spots to apply small patches.
Even w/bk cab wall left to do, i'll still have enuf to do ALL again. Just to use it up, might apply small patches on inside of inner door sheet metal-...
