The only thing that no one has said is !!!
Do you remove the dense foam inside the speaker holes, after you have taken off the blanking plates,To fit the new speakers ?
or do you leave it there ?
That is saying, you had not got the premium sound system fitted to yuor car start with (bose).
Because some cars left the factory with only the front door speakers fitted,and no rear speakers.
I hope this makes sence |
