Updated audio now going in to the 410.
The speakers are Alpine S-S69C on sale at £84 for the kit including tweeters.
The wooden supports are made to the same size as the original internals for the ash tray so are held in place by the spring.
The low/mid range units under the rear seats will have a perforated stainless grille and be covered with speaker cloth to match the carpet.
