Wire tracking help needed

[BolanHD]

I bought a sub and amp for my 2005 Clio mkII I have wired the red cable to the battery and need to track it back into the boot what's the easiest way to get it from the engine bay to the actual car interior?

I know the fuse box is to the left of my glove compartment but does that mean there is a easy route there?

​Thanks
