Hi all, I have a mk3 gti 3 dr and only have speakers in the front, 2 x door mount and 2 x dash mount, as you can probably gather this sounds cack and i would like to add some speakers to the back wether it be parcel shelf or mounted in the sides below the rear windows. Can you fit speakers in under the window as i would rather do that than cut holes in the shelf. When the speakers are in i am going to buy an amp to run them and this will be mounted on the underside of parcel shelf im not into loud bass or anything like that as the misses drives it more than me and she wont appreciate quality sound if it jumped up and bit her backside. Basically all i want is a surround sound system without my ears bleeding. Any advice or photos would help . cheers
