I thought of using namda or any sound deadening sheet behind the door cards....but surprisingly the car has become much quite than before.
Yes there is space where we can do some sound deadening but i will surely do in steps as :.
Speaker install'
Door lights
while doing the above two the sound deadening process.
Basically i want to see them fit and to use for some time so i get to know their flaws and problems......but untill now all is good. so will do the DIYs in the coming times. When u spend so much time tinkering with your car....your muhalla wala starts to think u are a mechanic
