yo, I'm new to this website and also new to the car scene. I have just got hold of a Seat Arosa MK1. I have recently bought a sub for the car and I'd like to know where to feed the power cable through. I have found a rubber grommet type thing with wires already entering it. (THIS IS TO THE LEFT OF THE ANTI FREEZE) When I poke a screwdriver through to try and find it there's no sign of it in the passenger footwell! I know there is already threads about this but I can't seem to find any on a MK1. Any help would be appreciated, thank you!
