Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

i have a 3dr corsa and the previous owner had been mucking about with the speakers and for some reason the front speakers arent working
im fitting my own cd player soon so was gonna upgrade the front speakers anyway
was just wondering what size the standard speakers are as im new to the forum and not sure if there is a sections with the sizes already listed
thanks in advance

The front speakers are 17cm, autoleads do a 17/13cm mounting kit for the corsa (SAK-3001 I think?).

ok thanks alot,
ive ordered some now so i hope i got them right lol
