Dude this sounds like a fookin stupid question, your power lead from the battery! Where did you bring it thru the bulkhead? I was going to wire my amp in today, but couldn't see a easy access / grommet to use! Decided to leave it for another day
ye look to the right of the engine bay and you will see a sort of oval rubber i have mine goin thru there and den have it run accross to the center console and under the carpet and rear seats into the boot
