Routing Sound Wire From Glovebox

Not sure if this is in the right section.

I've made up a ipod dock line out connector, and I need to run the wire from the glove box aux input down to where the ashtray is. All the panels seems pretty solid and wont come off like in my VXR haha

Any tips on how to do this?

I've pulled the screws from the glovebox housing, it's slid out like 5cm and now it wont come out any further.

Thanks
