First relocate this ground, make sure its proper or you will get strange interior lighting behavior.

Tuck away cables as shown and remove/cut/dremel the old ground bolt out of the way, same goes for the flanges on the rear arch as shown.

Now unplug the alarm, unscrew it and screw it in the other way around as shown and feed the wiring for it behind the panel as shown.

Now the central locking pump must be tucked in tight to the left between this flange and the boot body like shown below.

Box needs to sit just below this bump in the body. I personally also used this bolt for mounting the box in place.

Should look something like this.

Rest to do and end result.

You can get the box directly from Basser here http://sklep.basser.pl/en/fit-box-enclosures/49-fbaudi01-audi-a3-8l-fit-box-subwoofer-enclosure.html

The sub I used was a JL Audio 8W3v3-4 but any 8" driver will obviously work.

Have a great weekend everyone.
