If we are talking about front drivers doors. At first you have to remove dash with knobs. It is simple pushing up. Better to be warm, because plastic is very sensitive in Skoda. Under you will find screws. Not for sure but as remember there are screw under the hight frequency speaker. Grill is removed simply taking it out with plastic remover or knife of simple screwdriver. After that you will have to take the trim out. Trim holds only on plastic holders. (I have broken couple). Hope this helps.

This is already second car where I have installed Hertz. And second time satisfaction. The price and quality is the best what I have found and tried in this price category. For sound deadening I have used material from store which use it for air conditioner in buildings. Used something about 1,5 -2 m2 for 4 doors. I paid for all material used for installation 50EUR. This is really small amount of money and quality what I get.

I will try to put all in pictures and some comments: New speakers: Hertz Dieci series DSK 165 (sounds perfect from original Stream MP3) Used vibration isolation for external panels and a little for internal. Used noise isolation for all 4 doors and some in back. For Trunk isolation used a little bit different noise isolation. Sounds much better and less noise from outside. If any question please ask.

How did you connected Sub to original audio?
