as above any one ever done it befor, can it be done and what to use.

i think the kk5s have speakers there as std, so you could use those and just run some wire up to them, would be worth fitting the mk5 front door cards (these take a bit of work to fit) too though as it might look strange otherwise

i did it on my mk2, made up some cards and recessed the speakers but it stopped the back seats going down fully, keep your eyes peeled for that.
