ford ka rear speakers

[marco_v]

there are no rear speakers in my ford ka so i want to install a set of 6x9s. there is no factory speaker wire so i will have to install my own, this is the problem. i found were it goes in the connector block attached to the headunit but i dont know how to attach it, can anyone help me with this? also, what wire should i be using for this job? the factory wire for the front speakers is quite thin and fits into the conector block easily so im guessing the rear speaker wire need to be the same gauge?

Speaker wire is 2 core flat.. you should be able to get it from somewhere like Maplins.. yes, same guage.. unless of course you're going to run a massive amp and boom box.
