Pretty sure they are 15cm diameter front and back.

I would check but its raining outside.

Maybe later when it stops.

I think they are 4" upfront and rear are oversized 6.5" (6.75")

I have read that 6.5" will just drop right into the rear but you need to mod the door a little for this size up front. I can not find what the stock size is up front but, have found some stock pic's for you here http://www.mkiv.com/techarticles/parts/spe..._sub/index.html

Hold on, just found this:

The most straightforward replacement is a 4" speaker, (10cm). Even then you'll need to drill new mounting holes.

A 13 cm requires you to make a small mounting plate and do a little cutting of the OE speaker box.

17cm requires lots of modification or fabrication of a completely new speaker box. - Or, mount the speaker to the door card by removing the factory grille. - this is not the best way and if you take this route, be sure to dynamat the doors internally, get some foam/rubber gasket sealer to run around and seal the speaker better, and ideally make a wooden spacer to mount to the door card and angle it so that the speaker fires accross rather than down.

6.5" - R / 4" - F or 6.5" all round ?

I think you can get cheap BOV's but, don't know of any.

They are normally £200+ and you get fitting instructions with them AFAIK.

Some trader's who I have used before..
