Firstly chose Dynamat but got this as an instead due to no dynamat in stock, but wow this is what I was looking for with the bass and sound deadening! Great stuff! Would choose over Dynamat 100%

This is often a overlooked part on many installs. Sound deadening acts as a defence against intrusive road noise and also allows a more 'solid' mount for your speaker to reproduce their sound more clearly. This DQ1 is a good quality product, 1 pack can be enough to do 2 doors quite easily. On big bass systems this can aide in reducing panel vibration and overall sound loss.

  • Question: 08 July 2017
    Car: Audi TT - 1999-2006 (8N)

    Hi, is the sound deadening fixed to the inside of the door or the door panel?
    I also wish to upgrade the speakers, can I buy the adapters separately and choose from a range of speakers?


    Sound deadening needs to be applied inside of the door. You can purchase the speaker adapters separately. Speaker adapters are listed below for you.

    Does this have to go all over the inside of the door or just over part of it behind the speaker?

    This is down to your self, More you cover the better it will sound as it will deaden more of the door.

    I have ordered some In Phase Dead Quiet Sound deadening but have received what looks to be a German equivalent of this, could you explain why this is?

    Hi, did you order this online?
