mk4 rear speakers

[saitek]

hi one of my rear speakers in my mk4 gti have blown. can i buy a replacement standard one from anywhere?
if i cant do i need these adapters ive heard about to fit aftermarket speakers to the rear?

From memory think they are 6.5", would buy after market one's while they're out. If there isn't a square of factory sound deadening behind it, put some Dynamat or brownbread there, it'll improve the sound no end.

Hope this helps.
