Yes ours are blown too.... Are these the model you purchased and how much did you pay? https://www.jbhifi.com.au/gps-car-au...eakers/466362/
How hard were they to install and did you have any issues fitting them? Also once you had the door trims off was it simply a matter of removing the screws on the old speakers and screwing the new speakers on - all the screw holes lined up the same between old & new speakers and wiring terminals the same?
