my
Ateca speakers in the rear door need replacing as they are blown. Anyone know where I can get them?
It's the woofer not sub woofer. I'd sweet talk the parts number guy in a dealer and cross check. There is (was) a Seat parts sponsor on the board as well to buy from. The part number is the key. Google on the part number. There are parts web sites that come and go on the Internet which break Vag copyright, Russian but easier to get the part number off the parts department which has a legal online
resource. It will be a common part between the Vag brand.
Blown suspect you mean the diaphragm has gone rather than a cabling error, someone has had it turned up too loud. You'd want to change the matching pair. The old days of paper speakers people would blow them in cars. I've been in cars with blown speakers with a team member. I would have thought the diaphragms would have held out better but probably not if driven too hard. We had a posh Mission speaker with a resin cone blown once so those polymer cones do go.
Entry point for hours of enjoyment

I'd still check thou if anything has changed.. These are the 2016-2020 pages of the parts catalogue that get re purposed with adverts and links by operators.... as said the sites come and go. I'd ignore the links out to guys and just concentrate on the numbers.
