I fed mine down the side of the car under the plastic trim then to get in to the boot I slid the cables down the side of the seat where the back folds down, you could see them and it work really well.
managed to get it , forgot there was a bolt near the centre , all installed but fed up of it now , just not into loud music like i was a few years back
