Hi I have an older passat, model Arriva year 93. I would like to install new boxes because the old ones with my new cd-player are hopelessly overwhelmed and start to crack. I will install new boxes in the demanding doors which actually does not pose a problem. However, I go completely in the dark, where I find suitable and especially suitable boxes for the amature board. However, all my research has not yet produced any results. I’d be very happy to help you.
