I've just brought an Astra Coupe, and want to upgrade the speakers. Are they 17cm front and rear? Do I need any adaptors to fit the speakers or will they screw straight in to the fittings that are already there?
Also I've got a Pioneer fold out screen connected to a sat nav unit that plays dvd's. Is there anyway that I can put music videos onto a cdr and then play them through the screen rather than just listening to the music? I use Nero to write my cd's, is there something on there that I can use to make it work?
