im sure there is a 12v power cable located in the boot section that you can use to power your amp saving you alot of time and grief...
Ow yes their is
behind the panel on the right hand side of the boot is an orange cable with a live 12volts coming from it,
see a picture of it in my guide listed below this post, on fitting an additional 12v socket in the boot of your focus. if your taking a feed from it id recommend using some 15 or 20 amp cable with a male spade connector on the end and plug it in to the orange plug that is currently on the end of the orange feed in the car behind the panel,
then connect the other end of the 15 or 20 amp cable to your amp
