Hi i have a 2005 audi a3 5 door sport fsi. I am trying to wire an amp/sub in the boot. I have a 4 gauge wire to power amp but i do not know how to get from the battery all the way to the boot. where are there grommets from the bonnet area into the cars dash? Please help.

Is it behind the driver side carpeting ? Or how do i access it ? Do i need to drill through to get the wire through?
