Hopefully in the near future I will be installing carpet in my coupe. Was wondering what everyone else was doing about underlayment. I’m going to install the hushmat throughout and saw from several vendors online, jute backing about 1/2” think. Should I install separate jute backing then just carpet with no backing, or the mass backed carpet with the separate jute backing, or just the mass carpet over the hushmat? Appreciate any help, also what type of carpet, I see stuff called rayon,nylon 80/20, loop etc
