Glanza drivers will not understand the pain in the ass that is removing a GT passenger side speaker..
As an EP82 owner you have to put your hand up the back of the dashboard next to the glovebox and unscrew the speaker by hand. You will be working upside down, back to front and essentially blind. Don't let the bastard beat you.
Good luck..
Leave them in and put your speakers on your doors...
The speakers were £1100 and the'res another £2.5k of high fidelity equipment driving them.
i'm sure they're 10cm speakers.
