A6/S6/RS6 standard speaker sizes

[GarethRS]

All,

I've searched and searched and I know I have read somewhere, but I cannot seem to find the standard size of the speakers on my RS6.

I "thought" it was 130mm in the front and 160mm in the back, however all the speaker spacers you can buy says 160mm in the front.

Can anyone help before I have to remove my door panel to check?
thx

Just taken the door card off and the front speakers are infact 6.5" ones, so the Infinity reference 6510cs speakers I have will be an exact fit.

Not checked the rear doors yet, but i'm guessing they should be the same.
