Hello
In need of some new soundz in my mk2. I have a late mk2, so have six speakers (dash, door and rear)
Ive put some alpine 10cm ones in my 85 gti and they sound the good.
So am going to go with them for the dash, also seen alpine 13cm ones at halfrauds for £40, so fixed with them.
Now the rear

Can I fit 6x9 in there ?? Im not talking about direct replacment, as the standard are 6x4, but if im make some sort of braket will they fit ??
And I have a pants sony cd headunit atm 45wx4

Looking to upgrade my headunit to handle the above. budget isnt very high £100 for headunit ??. IM NOT looking to put a amp/sub in.
And sugestions??
