easy fix,- dealer just replaces subs under warranty.
Dealer may not have subs in stock and would have to order.
You should have your M3 back and drive it while you waiting for subs.
Dealer can only order subs once they determine it is subs that needed to be replaced... no biggie.
Please PM me if you have any questions!
It ended up as a blown amp. Sub's are good.
