bought these audioscape style door pods from another member, pics below.
i have finally got round to buying some decent competition grade speakers to replace some crappy SPLX ones which have been fitted until now. problem is, neither set of speakers generate any bass when mounted in the pods, i have checked phase etc and its not that.
i'm assuming the door card is absorbing the bass? do i dynomat the door card behind the speaker? or do i cut a hole in the door card immediately behind the speaker to allow more air to vibrate, and dynomat the inner door skin?
