Changing Head unit

afternoon folks,

Ive been searching all morning but i cant seem to find any help with this.

I have a 55plate a3 s-line i know it has several amps but i dont know if the whole car is amped or just the rear (and sub)

I have a sony BEX head unit that i had in my old car and i would quite like to see if i like it in the audi but i dont have a clue how to connect it up from what i can tell there are 4 iso plugs in the a3? and where the heck do i get a surround to replace my concert II.


Thanks in advance peeps


FL1X

basicly there is sod all point changing it

shame really i miss my head unit

Is there any way to wire it up so that everything works, preferbly without hard wireing as that just makes it a bitch when you want to change it agian.
