hey guys im kinda new to citroens, i have recently bought a very nice M Reg 1.9 TD and was planning on upgrading the ice in it. i have started off ok, with the head unit and front speakers, the problem is there is no rear speakers, and i cant figure out where the wires from the cd unit run to as they must be in the car somewhere. There are no other speakers in the car apart from the 2 mounted in the front doors can someone please help me and tell me where they go and what colour they are, or just give some tips about adding rear speakers thanks guyz
