    Hello....

    Have recently installed....

    Becker Grand Prix h/u
    Pioneer G-D515 5 channel amp
    Pioneer custom fit comp speaker x 4 receiving 60 watts rms
    RE Audio DVC 12 inch Subwoofer receiving 300watts rms wired in parallel
    Stinger wiring kit 4awg
    New speaker wire added through out

    Sound fantastic, but on a very smalll amount of bass heavy cd's such as Massive Attack im getting some vibration via the door skins

    Has anybody ever sound dampened/deadened a b6 A4 door?
    I have read on another audio forum that one trick is to apply expanding foam between inner and outer door skins and also to apply dynamat to wherever possible

    Or a combination of both

    Anybody any ideas????

    Expanding foam is an excellent idea if you no longer want to use the windows. Who on earth recommended that?
    Dynamat should be used wherever possible, but the vibration is probably more to do with the door cards than the doors themselves.

    LOL....I was wandering about the windows myself, but thought they might slide into an area where the expanding foam wouldnt reach......ill try and dig out the link for you, was quite a comprehensive guide.

    If i do dynamat the doors do i remove the foam/rubber type stuff that already cover the interior door skin or ios this not advisable? could i dynamat the the door card?

    Or turn the volume down a bit. After all, it's a car, not the Roundhouse.

    I wouldn't bother, the main culprit affecting the sound is the external door skin, which unfortunately you can't get to.
    Extreme sound deadening is really only beneficial on competition spec systems.
