    Sound deadening, where to start?

    Im looking at sound deadening my astra coupe, mainly to reduce road noise. And i was wondering where the best place to start is.

    I want to make as much difference to road noise as possible, so wheres the best place to start? The floor? the door?

    Thanks.

    do the bits that have no deadening from the factory

    Roof, doors, quarters. Then if you wanna go mad, do the floor, bulkhead, bootfloor

    Which part is the bulkhead? And what makes the most difference? Places that have no deadening from factory?

    Cheers Dave.

    the bulkhead is behind the dash, the firewall.

    the bits that will make most difference are the biggest most flexible pieces of metal, These are the bits that will vibrate the most which is what you hear as road noise
